Manjal Shah
Thanks, Manjal. I'd like to welcome everyone to today's call. We finished calendar 2021 on a strong note, and I'm proud of what we were able to achieve. We capitalized on our market opportunities while navigating supply and logistics challenges. We delivered double-digit revenue growth in 2021, while still managing to consistently improve gross margin. Revenue for the December quarter was at the midpoint of our updated guidance with continuing strength in our IoT products. Our GAAP and non-GAAP gross margin was another record for the company. Higher revenue and gross margin in turn drove our quarterly non-GAAP operating margin and non-GAAP EPS to record levels as well. Our momentum remains strong, and we're seeing many growth drivers, particularly in IoT applications. Our design wind pipeline remains robust, and we see continued opportunities to cross-sell our products, driving our dollars per platform higher. Our customers are introducing new, digitally enhanced products that are smarter and more connected than ever. At this year's CES show, several products, such as IoT Home Hubs, smart cameras, wireless workplace configurations, smart doorbells, and smart monitors were announced and feature our semiconductor solutions. In early December, we completed the acquisition of DSP Group and welcome a talented group of unbelievably capable engineers. We expect the team to accelerate our product roadmaps in the areas of wireless, home security, and low-power edge AI. The learning that DSP Group has had on voice-enabled AI products will serve us well as we embark on tackling the even more promising long-term opportunity applying machine learning to simple computer vision applications. Our integration is on track, and we are already seeing the benefits of the two teams working together. Synaptic's larger sales force and strong customer relationships are bringing DSP Group technology into new accounts that were not previously accessible. Meanwhile, we are seeing pull-through of Synaptics technology, particularly wireless, on existing DSP Group platforms. Our IoT products are now at a milestone $1 billion annual revenue run rate, growing 60% year over year, and accounts for 62% of our total revenue. Wireless continues to be the fastest growing piece of the IoT portfolio. New sockets are being unlocked as IoT customers begin the transition to Wi-Fi 6. Wi-Fi 6 is particularly well suited for IoT devices because it allows a greater number of products to connect to the network simultaneously without any one device being starved by other high traffic units on the same network. The technology also enables low power consumption, which is particularly critical in battery-powered IoT devices. Our competitive differentiation is strongest in high bandwidth, low power applications because our Wi-Fi 6 products are 90% more power efficient compared to prior generations and 35% more efficient than competition. We have design wins across a variety of product categories, including surveillance cameras, drones, smart displays, gaming, wearables, smart speakers, and other consumer-centric devices. Our industry-first triple combo wireless device is being sampled, and we expect initial revenue toward the end of the calendar year. The product is based on the Wi-Fi 6E standard enabling devices to operate at a higher frequency band where there is less congestion. We are making organic investments to grow the business, deploying new engineering resources, and are happy to report that we now taped out two new products based on our internal efforts. With our strong momentum, we remain confident in achieving our target to double our wireless revenues again. Our video interface products continue to lead the market, and our latest innovations are creating distance to the field. Our newly announced wireless docking solution simplifies the work area and was demonstrated at CES this year by one of our largest customers. We're excited about the potential of this new class of product as it enables improved productivity for end users and flexible workplace configurations for enterprises. The solution is a prime example of our ability to cross-sell multiple technologies, in this case combining our wireless connectivity, video compression, and processor expertise. In the protocol adapter and converter market, we're seeing early traction as we enter a completely new market opportunity. We have introduced two devices in recent quarters which open up that additional TAM and now have a dozen or so design wins ramping over the next few quarters. Our differentiated solution is a single chip offering that lowers power consumption by 75% and reduces overall footprint by 60%. We're seeing terrific market traction in virtual reality headsets with continued revenue growth and design win momentum. We are winning across the board, including many VR manufacturers in China. Our display technology is the highest performing custom design for those headsets and is the first and only solution in the market that supports a total resolution of greater than 4K with refresh rates of 120 hertz. A high refresh rate is essential for smoothness of motion as it allows for higher frame rates and lower latency that are both critical to ensure a more realistic VR experience. We are continuing to invest in a future roadmap that features even higher resolutions and refresh rates as well as leading the transition to newer display technologies such as micro-OLED. The market is still in its infancy, and we feel confident about our position, market potential, and the strength of our roadmap. In automotive, we achieved our goal of $100 million in annual revenue run rate, two quarters ahead of plan. Our automotive TDDI products are now designed into more than 50 car models across 20-plus OEMs, and we are seeing production ramps at six OEMs in Europe and in Asia. We are very well positioned because our share of TDDI-based solutions is much higher than our share in a discrete implementation, and the market mix of these devices, though relatively small, is increasing rapidly. In fact, nearly all new designs are being initiated around TDDI technology. Moving on to our processor technology, we now have a complete suite of products that range from ultra-low power solutions that run simple machine learning models to complex, high-performance video decoders that feature neural networking capability. We believe every consumer edge device will become more intelligent, driving the need for task-specific processors with artificial intelligence extensions rather than general-purpose microcontrollers. Our processors are targeted at audio and video applications, event detection, and with the addition of DSP Group, low power edge AI use cases. Our AudioSmart family of processors are being designed into headsets, tablets, smart monitors, and docking stations and boast a compelling combination of integrated voice features, noise cancellation, and low power consumption. Our video smart series combines a high-performance CPU, GPU, and neural network processing unit into a single software-enriched SOC and complex applications such as smart signage, sound bars, and video conferencing systems. Finally, our Katana processors feature the ability to run both voice and vision machine learning models at very low power levels. At CES, we announced our first significant customer, Lenovo, utilizing Katana in one of its tablets. We are encouraged by continuing early indicators in the low-power edge AI market and remain excited about its long-term growth prospects. Let me move on to our PC product applications. After two years of strong growth, we expect market demand in calendar year 2022 to remain about at the same level as 2021. Within that, The expectation is for commercial market shipments to be a bigger part of the mix, which plays to our strength. We are gaining share in PCs because of our technology and innovation. At CES, we launched our latest system on chip that enables the design of larger size touchpads with haptic capability. It's the first device to comply with the NIST SP800-193 standard, and we feature 384-bit encryption, reducing external threats on the PC. We began shipping this device in the quarter and expect all our major customers to design it in during the calendar year. Finally, in mobile, many new models from Chinese smartphone manufacturers using our touch technology launched in the last few quarters, but it appears the end demand for some of the OEMs didn't materialize as expected. On the other hand, we began shipping production units of our new high-end flexible OLED display driver in the quarter, which adds yet another growth factor for Synaptics. Before I conclude, let me give a quick update on our supply chain. In general, supply remains tight. In our case, the constraints are most prevalent in newer, faster-growing areas of our portfolio, where new design wins are significantly outpacing any incremental supply we're getting. We expect challenges in all facets of the supply chain, wafers to back end, to persist through all of calendar 2022. To conclude, Q2 was yet another in a series of strong quarters for the company. We set multiple corporate financial records in the quarter, particularly around gross margins. Meanwhile, we continue to grow top-line revenue by both developing entirely new product categories and executing well in our core business. Now, let me turn the call over to Dean to review our second quarter financial results and provide our outlook.
AudioSmart
Thanks, Michael, and good afternoon to everyone. Before I begin, I'd like to remind everyone that our Q2 results and Q3 guidance include the impact of the DSPG group acquisition, which closed on December 2, 2021. Integration of this new team is well underway. We have successfully migrated all major DSP group systems and processes to the Synaptic platform, and our $30 million operating cost synergies are on track. Moving on to the fiscal second quarter results, revenue for the quarter was $421 million. at the midpoint of our updated guidance. Revenue was up 13% sequentially with strong demand for the company's IoT products and was partially aided by the DSP Group acquisition, which includes approximately one month of contribution. Revenue from IoT, PC, and mobile were 62%, 20%, and 18%, respectively, in the December quarter. Year over year, the December quarter revenue was up 18%, driven by growth in our IoT revenue, where we are continuing to focus our efforts. Our IoT product revenue increased 60% compared with the year-ago quarter, and up 27% sequentially. Our revenue momentum in this area continues to outpace almost all peers and is now at a milestone $1 billion annual run rate. Our mobile and PC revenue declined year over year due to timing of certain programs. PC product revenue was down 7% sequentially and down 10% year over year and was impacted by continuing supply chain shortages for certain components at our customers. Our PC demand over the last six to nine quarters, six to nine months, excuse me, has been relatively flat as we continue to see a stable commercial market. Our mobile product revenue declined 3% sequentially and declined 26% on a year over year comparison due to a prior product transition with a certain customer. During the quarter, we had two customers greater than 10% of revenue at 13% and 12%. For the December quarter, our GAAP gross margin was a company record at 53.5%, which includes $19.9 million of intangible asset amortization, $4.1 million of inventory fair value adjustment, and $1.3 million of share-based compensation costs. GAAP operating expenses in the December quarter were $147.5 million, which includes share-based compensation of $35.3 million, acquisition-related costs of $10.4 million, consisting of intangibles amortization and transaction costs, amortization of prepaid development costs of $2.5 million, and restructuring-related costs of $5.1 million. Our GAAP tax expense was $2 million for the quarter. In the December quarter, we had GAAP net income of $69.5 million or GAAP net income of $1.71 per share. Now turning to our non-GAAP results. Our December quarter non-GAAP gross margin of 59.5% was a new company record and at the high end of our guidance range. reflecting a continued strong mix as we prioritize our highest value products while passing through changing input prices. December quarter non-GAAP operating expenses were at the low end of our guidance at $94.2 million and up $5.8 million from the preceding quarter due to the partial inclusion of DSP Group. Our non-GAAP operating margin of 37 percent in the quarter was another record for Synaptics. Non-GAAP tax expense was $18.1 million for the quarter. We had record non-GAAP net income in the December quarter of $132.8 million, which is an increase of 22% from the prior quarter and an increase of 58% from the same quarter a year ago. Non-GAAP EPS per diluted share was $3.26 as our focus on profitable growth continues to drive positive earnings for our shareholders. Now turning to the balance sheet. We ended the quarter with $574 million of cash, cash equivalents, and short-term investments on hand, an increase of $227 million from the preceding quarter as a result of strong cash flow from operations of $122 million and the inclusion of cash and investments which were acquired as part of the DSP group transaction. Receivables at the end of December were $312 million and days of sales outstanding were 67 days, up slightly from 65 last quarter. Our days of inventory were 70, up from 51 last quarter, and ending inventories were 133 million. This includes an increase in work-in-progress inventory as we pipeline material for our growing revenue projections and the inclusion of the DSP group inventory, which includes the purchase price accounting step-up. Normalizing for DSP group, inventory days would be approximately 60 at quarter end. Despite this sequential increase, we expect inventory to remain low given our revenue and shipping forecasts, while our supply chain constraints continue to depress inventory below our desired level. Capital expenditure for the quarter was $8.5 million and depreciation was $6.4 million. We anticipate revenue for the March quarter to be in the range of $450 million to $480 million. Similar to last quarter, our backlog at the start of the quarter was above the high end of our guidance range as we are still supply constrained, limiting our ability to service our customers' full demand. Further, our demand signal continues to be strong as our backlog position has expanded and is now higher than it was when we met one quarter ago, excluding any M&A-related backlog ads. We expect revenue mix from IoT, PC, and mobile products in the March quarter to be approximately 63%, 19%, and 18% respectively. We anticipate our IoT products growing almost 100% on a year-over-year basis at the midpoint. significantly faster than the broader market and faster than all of our IoT-focused peers. We expect our GAAP gross margin for the March quarter to be in the range of 52.5% to 53.5%. We expect our GAAP operating expenses in the March quarter to be in the range of $159 million to $166 million which includes acquisition-related charges for intangibles and transaction costs, prepaid development cost amortization, share-based compensation, and restructuring costs. Finally, our GAAP net income per share for the March quarter is expected to be the range of $1.25 to $1.55. Now, non-GAAP outlook for our March quarter. We expect non-GAAP gross margin momentum to continue into the March quarter. We expect non-GAAP gross margin in the range of 59.5% to 60.5%, which at the midpoint of 60% would be a notable milestone achievement and representing one of the greatest gross margin expansion success stories across the semiconductor industry. We expect to continue prioritizing our focus and delivery to a robust and positive mix while continuing to navigate supply chain constraints and changing input prices. We expect our non-GAAP operating expense in the March quarter to be in the range of $104 million to $108 million, an increase from the December quarter as we now add a full quarter of expenses related to the DSP group acquisition while continuing to self-fund our organic growth opportunities. We expect our non-GAAP interest expense to be approximately $8 million in the March quarter. As a reminder, our interest expense is higher due to debt financing related to closing the DSB Group acquisition. We expect our long-term non-GAAP tax rate for fiscal 2022 to continue to be in the range of 11 to 13 percent. Non-GAAP net income per diluted share for the March quarter is anticipated to be in the range of $3.40 to $3.70 per share on an estimated 41 million fully diluted shares. This wraps up our prepared remarks. I'd like to now turn the call over to the operator to start the Q&A session. Operator?
Operator
Thank you. As a reminder, to ask a question, you'll need to press star 1 on your telephone. To withdraw your question, please press the pound key. Please stand by while we compile the Q&A roster. Our first question comes from Raji Gill with Needham & Company. Your line is now open.
Raji Gill
Yes, thank you, and congratulations on stellar results. Question on the IOT, the growth that you saw in the quarterly 60% year-over-year and the growth that you're expecting in the March quarter up 100%. I'm wondering if you could maybe describe, you know, some of the sub-segments of IoT which is driving the growth. You know, for instance, last quarter you mentioned virtual reality, headsets adding to the IoT number. You're talking about automotive growing kind of faster, wireless connectivity. I'm just curious how you would kind of segment those particular areas within IoT and how we think about those segments, not only in the March quarter, but kind of progressing throughout fiscal year 22.
Manjal Shah
Yeah, Raji, I think your question actually touched on the three that I would pick as being the big growth drivers, and that would be first the VR goggles segment, Obviously, we have a large customer in that space that's doing really well, but I think we talked about in the prepared remarks is the fact that we're winning everywhere, and now Chinese goggles are starting to come online and drive some pretty good volumes. So I feel good there. The second one you touched on is automotive, and the issue there is, We're going from a world of these discrete chips that touch and display drivers, discrete touch and display drivers, to TDDI. And while we participated in discrete touch and discrete display drivers, we had relatively low market share. As the market begins to tip toward TDDI, we have high market share there. And, you know, as that becomes the preponderance of the units that ship, we expect we're really going to do well. And then the last one also you touched on, which is the wireless products. You know, we're winning there. It's our Wi-Fi Bluetooth combos and then a mix of our standalone GPS products that are really driving the results. So those are really the three areas. Of course, you know, our other businesses are doing pretty well too. In fact, there's not a single area in the IoT portfolio that I could point to that was showing weakness.
Raji Gill
And that's excellent to hear. And then on the supply situation, you know, last time we spoke, the supply situation remains tight. You are in the process of consolidating your foundry partners. You had mentioned in the past that you had as many as 10 foundry partners. but you're in the process of consolidating those to a few. So I wanted to get an update in terms of how you're looking broadly at your supplier relationship. Are you confident that you'll get the extra capacity as the year goes on? And, you know, are you going to be able to get capacity for some of the new products and the new areas that you're focusing, for instance, the Wi-Fi protocol chips versus the more mobile-orientated chips?
Manjal Shah
Yeah, again, excellent question, Raji. I say the following. I mean, certainly we feel like we can get incremental supply that supports the guidance and keeps us optimistic about the future. That said, you're absolutely right, and we touched on in the prepared remarks, our biggest challenges are all these new growth areas for us. because our demand is outstripping our ability to get incremental supply. So I think Dean talked about even some backlog accumulation in his remarks, and we see that in Wi-Fi. We see that in the VR goggles. We see that in automotive. We see that in these protocol adapters. So in all of these areas where we've got effectively new categories of products, we're having the most difficulty keeping up with supply, but we are able to get incremental supply here and there, and that gives us some confidence that we're going to be able to continue on this growth factor that we've outlined.
Raji Gill
Great. And just one more question if I could squeeze in, and I'll step back in the queue. The gross margins, 60%, you know, just phenomenal margin expansion the last, you know, couple, few years. The 60% margin for March, can you talk about what's driving that, both on a fundamental basis? Perhaps you can talk about the contribution that DSP is having. But even putting aside DSP, it does imply that the margins within the different segments, you know, IoT, mobile, PC, have been improving significantly. Obviously, the next question is, you know, how much of that is price increases? I know you talked about that you're passing the input cost in the form of price increases. So I would assume that would be neutral to the margins. But can you discuss how price is affecting your margins, if at all? Thank you.
AudioSmart
Yeah, Rajit. So on pricing... Well, I'd say that's largely, you know, margin neutral. I mean, where input pricing has gone up, you know, certainly we've, you know, had to price, you know, pass it along to many of our end customers, but it should be thought of as, you know, margin neutral. Really the margin, you know, increase as we guide in into the March quarter is all around mix. So one, as our IOT portfolio continues to grow, Those are a number of product areas that actually are margin accretive for us. But all areas of the portfolio have been improving their margins over time, as really our focus has been on selling the premium versions of products in all of the market areas. So the more premium devices in PC, we're going after premium things in mobile, and of course many of the premium areas in IoT And so that's sort of been our fundamental shift really over the last couple of years, and that's what you're seeing here going into March.
Raji Gill
Great. Thank you very much.
AudioSmart
Thanks, Raji.
Operator
Thank you. Our next question comes from Christopher Roland with Susquehanna. Your line is open.
Christopher Roland
Hi. This is actually for Chris, and thank you for taking our question. So I just want to follow up on the supply question earlier. You said your number one constraint is around the wafers. And we've actually seen some other companies either investing heavily into CapEx or just locking in wafers way in advance. So is this something that you're considering? And if you could just elaborate a bit more on your strategy here. Thank you.
Manjal Shah
Yeah, I think, you know, we obviously, where we can, we're looking at entering into these long-term agreements to try to lock up supply. You know, that's not consistent across the board. If we think it makes sense, then we will enter into those agreements. I would say that that's not universal. I mean, our tactic for the most part has been to work with key partners and sort of increment out this wafer supply. We're, of course, a fabulous semiconductor company, so we're not subject to capex per se. We're strictly a consumer, and it runs into the cost of goods line. So it's obviously a never-ending battle. We're doing what we can to increment our supply. And as I said, in certain cases, and you alluded to it, where we see opportunity, you know, we will look at and entertain long-term agreements.
Christopher Roland
Great. And then as a follow-up, you also talked about the Chinese handsome market being weaker than expected. So how are you seeing this and market demand here into the back half of the fiscal year?
Manjal Shah
Yeah, I mean, you know, obviously mobile is now a smaller part of our portfolio. We certainly believe in our roadmap. We're winning the majority of our touch sockets. We feel good about our position both in Korea and in China, as I think we've talked to in previous calls. Then what's the sell-through? And that's obviously harder for us to determine. There seems like there's some softness. But for us, it's a smaller part of the portfolio now. I think Dean talked about it being sub-20% of the overall mix. I'd say on the upside, we've got this new launch of our OLED display driver. Dean talked about it a minute ago in his comment. In general, in mobile, we're trying to go after the very highest end of the market. And this is a good example of it. It's a very high-end OLED display driver. And so now... In each handset, we have an opportunity, and particularly at the high end, to sell more content per phone.
Christopher Roland
Thank you.
Operator
Thank you. Our next question comes from Derek Soderberg with Collier Securities. The line is open.
Derek Soderberg
Hi, guys. Thanks for taking my questions. I actually want to start with ULE. You have some nice large service provider wins in the U.S. and Europe. I'm just curious how that ecosystem build out is progressing and, you know, wondering what's the best path to build out that ecosystem. Is it to sort of integrate ULE into other chipsets or simply cross-selling? You know, what's sort of the best path for driving growth in ULE?
Manjal Shah
Good question. I think that it depends on where it goes in the ecosystem. So we're just at the beginning of our ramp with one specific North American customer. And the opportunity is to go into these endpoints, window sensors, door sensors. That likely will be ULE only as the technology itself is really conducive to longer range, lower bandwidth types of things. So I think the sensor will ultimately be ULE only. Where you get into an opportunity to combine technologies is in the hubs. the thing that's controlling all the endpoints. And you certainly get into opportunities in things like surveillance cameras. So we are looking at certainly in the first phase cross-selling, cross-selling our Wi-Fi Bluetooth combos into those sockets. And then as that market progresses, we'll evaluate should we bring ULE into some sort of super combo chip to really create a defensible socket. As I say, I don't know that the highest volume piece of it will ever go to a combo type of solution because you kind of have single function out at these window break sensors and door open-close sensors.
Derek Soderberg
Got it, got it. As my follow-up, there's been some data out there that a good portion of growth has been from inventory build. Obviously, for you guys, March quarter looks like it's going to shape up nicely. But sort of beyond that, do you have any visibility into sell-through for IoT and PC? I think you mentioned some softness in mobile. Any visibility into channel inventories of some of your larger customers? And how are you factoring any of that into internal expectations for the year? Anything on that would be great.
AudioSmart
Yeah, Derek, I would say we have probably limited visibility into individual and customer's inventory positions. But what I can say is within our channel partners, the inventory remains very low. We don't really see inventory buildup in any specific area. I think the one exception is in mobile that you touched on, that that actually is sort of recently weakened for us. Outside of that, we don't see anything specific in IoT. PC continues to have occasional match set issues. I think you've sort of heard from others around that. But that doesn't look like inventory to us. It just is sort of an up and down on how they, you know, pull that inventory through to their factories.
Derek Soderberg
Got it. Thanks, guys.
AudioSmart
Yep.
Operator
Thank you. Our next question comes from Anthony Stoss with Craig Hallam. Your line is open.
Anthony Stoss
Hi, guys. My congrats, especially in the gross margin, improving from 40% to 60% roughly in two years. Pretty remarkable. Michael, on the IoT side, just phenomenal growth. How much of that is from content expansion or taking share? Also, where do you see content can go for you guys with more products heading in that market? And then for Dean, I'd love to hear your thoughts with supply constraints. Any view on... the June quarter, if you think it's going to be seasonal, above or below, or in line. Thanks.
Manjal Shah
Yeah, Tony, I mean, just to sort of talk about the IoT business, you know, we've talked about the growth vectors being the wireless, the VR, and automotive. I would say the long pole in our growth is actually new categories where we've actually gotten into new businesses for us. Those are really new businesses for us, particularly if you consider automotive, the shift from discreet, where we have been playing for a while, but really ramping the TDI solution. So in terms of the revenue line, I'd say that's the long pole. In other areas in kind of our core run rate businesses, we do feel like we've been taking historic share. You know, our video interface business continues to run really strongly, and we feel like that's a franchise business. But I'd really say the long pole in terms of growth are these new categories that are coming into play and creating new veins of revenue that we can go and mine.
AudioSmart
And, Tony, on your second question, which was around supply constraints, maybe beyond the March quarter, you know, we're sort of not – you know, taking questions beyond March at this point. But what I would say, you know, sort of looking out, our supply constraints are, you know, certainly a concern for us. You know, we would certainly take more if we could get it from our suppliers. But the backlog is extremely strong. In fact, backlog as we sit here today is actually higher than what it was a quarter ago. So you can sort of read that as sort of net New orders coming in are outstripping shipments going out. And then despite having a great December quarter and despite now with this guidance in the March quarter, that continues to be strong. So we're sort of sitting here and not concerned as we look out beyond March.
Anthony Stoss
Okay. Then if I could have a quick follow-up with Michael, shifting gears a little bit into the auto side. You guys have recently entered on the connectivity side. I'm curious if you can share any details on the traction you're seeing or really anything in auto.
Manjal Shah
Yeah, Tom, I mean, I'd say that that's not quite right. We're obviously looking at connectivity for auto, but we haven't entered there. Our focus has been on a lot more of these video transfer types of products, wearable products, consumer gadgets of different varieties. Automotive remains something we feel like we could go into if we want to, but at this point we're more in kind of a look through the window type of mode.
Anthony Stoss
Got it. Great job, guys. Thank you.
Manjal Shah
Thanks, Tony.
Operator
Thank you. Our next question comes from Carl Ackerman with Cowan. The line is open.
Carl Ackerman
Yes, good afternoon. Two questions for me, please. One for Michael and one for Dean. Michael, you spoke about now shipping OLED display drivers, which complements your OLED touch controller offering. I'm curious how you think about integrating both of those components that may allow you to broaden your mobile offering to new and past significant customers.
Manjal Shah
Yeah, Carl, I mean, we've talked about that. I think when I first got here, we talked about a mobile TDDI product for high-end OLED phones. As we got into it and we talked about in previous calls, I think we saw this real opportunity in OLED discrete, discrete OLED display drivers not doing a TDDI solution. Right now, I would say most of our bandwidth is occupied on a family of discrete display drivers. We continue to investigate TDDI. The opportunity for us in the engineering priority allocation has been on discrete, simply because we see a quicker path to entry there, a better process match in terms of the touch circuit and the display driver. and there's all kinds of new products that are opening up, the folds, the flips, the things like that, where it requires a little bit of nuance on the display driver. So I'd say that's where we're spending our time, although, to your point, I think you ultimately will end up combining the two technologies.
Carl Ackerman
Understood. Thank you. Dean. This is the first time you gave a number of car models you're designed into, if I'm correct. Are all these models ramping today, or is there a way to think about the step function of how they will ramp over this year and next? Thanks.
Manjal Shah
Yeah, Carl, I mean, let me just explain the numbers that we gave. I think we said we're designed into 50-plus models at 20 different discrete manufacturers today. Six of those are ramping now. So there's a lot that's future. They're design ins, design wins. They're not production. And we really try to characterize this market as really being in the early innings of a shift to TDDI. Most of the units that go out today are still discrete display, driver, discrete touch. But we're starting to see that tipping point. And certainly, as I said in the prepared remarks, most, if not all, new designs are TDDI-based rather than discrete-based.
AudioSmart
And just one quick data point for you, Carl. We have previously talked about sort of 40-plus models, and sort of the update here is now it's 50, so it's incrementally adding to our model count that we have previously.
Carl Ackerman
Helpful. Thank you.

Thank you. Our next question comes from Kevin Garrigan with Rosenblatt Securities. Your line is open.
Kevin Garrigan
Hi, guys. This is Kevin Garrigan for Kevin Cassidy. Thanks for taking my questions, and let me echo my congrats. My first one, there's an expected inflection point coming in the second half of calendar 2022 for new Android smartphone launches. Can you give us an idea of what the adoption rate of flexible OLED is for these new smartphones, and Has the competitive landscape changed in the flexible OLED touch market lately?
Manjal Shah
Yeah, I think our sense is that the number of flexible OLED displays are increasing and increasing, I'd say, not dramatically, but something short of that. So the mix is definitely going toward flexible OLEDs. We continue to have strength and advantage in flexible OLED touch controllers. So as the market tips that way, we feel pretty good. And then as we've characterized, the second driver in our mobile business is the shift from Korean displays to Chinese displays. And there in the Chinese displays, we think we have the opportunity to sell in that display driver. Again, it's the kind of the highest end of the skew stack.
Kevin Garrigan
Got it. That's helpful. And just as a follow up, you guys announced the wireless docking station reference design. Can you give us a sense of what the dollar content increases for you in a wireless docking station versus wired? And should we kind of view this product as cannibalistic to your current product line? Or is it kind of more market expansion?
Manjal Shah
Yeah, I mean, I'd say it's a little bit of both. I definitely think there's going to be some cannibalization. But we also think it's got features to open up a whole new market set. So I think it's a bit of both. And then I think on the second one, we're looking at, you know, tens of dollars on the content side that steps up from a traditional wire dock to go to one of these wireless docks. So... I don't know the exact numbers, but it's something north of 10.
Kevin Garrigan
Okay, perfect. That's very helpful. Thanks, guys, and congrats.
Manjal Shah
Thank you. Thanks, Kevin.

Thank you. Our next question comes from Martin Yang with Oppenheimer. Your line is open.
Martin Yang
Hi, good afternoon. Thanks for taking the question. I have one question for Dean. Can you maybe talk about the gap gross margin trend in the past quarter and also in the guidance? It feels like it's a tad lighter than your previous guidance for the December quarter, and March is another slight step down. How much should we read into this, and what are the reasons behind that gap margin trend?
AudioSmart
Yeah, good question, Martin. So the first thing to know is notable that The GAAP gross margin for the December quarter is actually a record as well for Synaptic. So it's trading sort of inline record on the non-GAAP and GAAP side at the same time. The December and even more so into the March guide for the GAAP gross margin is going to be highly influenced by the DSPG acquisition. So there are a number of inclusions on, you know, GAAP-related, you know, step-up and inventory value intangible amortizations that will run through the GAAP-only side. So you're going to see that effect, you know, for a couple of quarters until you get through sort of that initial amortization schedule.
Martin Yang
Got it. That's perfect. Thank you.
AudioSmart
Yeah, thanks, Martin.
Operator
Thank you. And our next question comes from Brett Simpson with REIT Research. Your line is open.
Brett Simpson
Yeah, thanks very much. I wanted to ask about the non-GAAP gross margins. You mentioned this has been one of the bigger jumps in the history of the semis industry in terms of the performance gains, and it's been a fantastic improvement over the last few years. When I look at the portfolio you offer, there's still a lot of and you're playing a lot of consumer areas where generally the returns are structurally lower than we would normally see, and certainly a lot of your peers would have lower gross margins. And so my question is, you know, the performance of the business has been fantastic, but really how sustainable are the gross margin returns across the business, particularly some of the new categories that you highlight start to mature? Thanks.
Manjal Shah
Yeah, I mean, maybe I'll take the first question. comment and then turn it over to Dean. Obviously, we feel good about the sustainability of the gross margin line. I think mostly because while you're right, the end markets in which we play are consumer, auto, where there's quite a bit of competition, we feel like we've got a level of differentiation, a level of integration, and a level of performance enhancement that gives us the ability to sell at higher ASPs than our competitors. We really do feel like the gross margin is something we worked on. We've worked on structurally since Dean and I got here, and we've obviously improved in almost every quarter we've been together. It's going to level off at some point. I mean, there's no question it's not going to improve at the rates we've seen, but I do think that it's something that's sustainable.
AudioSmart
Yeah, Brett, I think that's the important point to take across is that largely our products are aimed at premium portions of our end markets, sort of just broadly characterizing as consumer and low margin is not necessarily a true fact. In fact, we talked about, for instance, our areas of processors, right? We're going after things that are doing AI at the edge. video transport, decode, encode, audio with high-end features, wireless connectivity, Wi-Fi 6 and 6E, that's the cutting edge Wi-Fi standard today with lower power than any of the competitor solutions on the marketplace. Unique capabilities to transport video in a wired form factor. Even in PC and mobile, we go after sort of high-end commercial laptops. We're now integrating haptics, you know, type designs into some of our PC products. On the mobile side, again, it's aimed at flagship, you know, high-end flexible OLED, you know, type mobile devices where, in fact, the engineering is valued and the things that Synaptics can bring is valued by the customer base and, therefore, we can extract a reasonable gross margin. So I think that's the way to think about it. You know, bread is not necessarily sort of overly generalizing, but you'll think about it as the premium areas.
Brett Simpson
Okay. Thanks for that. And maybe just to follow up on, on pricing, I guess we've seen a big foundries, you know, TSMC is one of, one of your big foundries. They've been raising prices quite, quite meaningfully in going into 2022 and, And we're seeing a lot of chip makers are passing that on as they should if they can. Can you maybe talk about or give your perspective on how you're dealing with those cost increases? And when you look at that March quarter guide, how much of that sales increase is generally a pricing increase? Thanks.
AudioSmart
Yeah, so we're no different from many of our peers, and I think we've been pretty straightforward that we have seen input prices change significantly. in the past quarter, quarters before that, and we've incorporated any known pricing changes for our March quarter guide, we do pass along these price increases largely to our end customers. And so as input prices change, largely that ASP changes in conjunction. And it is actually an economics 101, right? You know, demand outstrips supply. You actually will see this phenomenon. So, yeah, we have been successful in passing that along, and we continue to do so if input prices were to continue to change. But it's fully incorporated into our March Guide.
Brett Simpson
Got it. Thanks very much.
AudioSmart
Yeah, no problem, Brad.
