SiTime Corporation introduced a new Automotive Oscillator family, based on SiTime’s advanced MEMS technology. The new differential oscillators are 10x more resilient and ensure reliable operation of ADAS across extreme road conditions and temperatures. The launch of the new Automotive Oscillator, AEC-Q100 SiT9396/7, expands the SiTime served available market (SAM) by $50 million.
“Indeed, the market for radar, camera, LiDAR, and computing for ADAS is accelerating very fast,” reports Pierrick Bouley, Senior Analysts at Yole Intelligence, part of Yole Group. “With a 13.2% CAGR, we see this market growing from $15.4 billion in 2022 to $28.6 billion in 20271.”
As automotive safety systems integrate more sensors and cameras, they are generating an explosion of data that is crucial for safe, autonomous operation. According to the Automotive Edge Computing Consortium, a vehicle generates 2 TB per hour today, increasing 10x to 20 TB per hour by 2025.
ADAS sensor data must be transferred at very high speeds within the in-car network, even in the most demanding environments, so that ADAS computers can make timely decisions for a safe, reliable journey.
Timing is the heartbeat of all high-speed communications. Legacy timing technology is one of the weakest links in today’s sophisticated car electronics. In fact, quartz devices are susceptible to vibration and shock, extreme temperatures, and exhibit performance degradation over time. SiTime’s new SiT9396/7 precision timing solutions, based on resilient and reliable silicon MEMS technology are designed to perform in extreme conditions and ensure reliable operation of ADAS computers, domain/zone controllers, radar, and LiDAR subsystems.
“As more cars are equipped with ADAS technologies, precision timing becomes a critical component for safety,” said Piyush Sevalia, EVP marketing, SiTime. “SiTime’s automotive-grade timing solutions mitigate safety and reliability challenges, delivering unmatched benefits to automotive OEMs and Tier 1 suppliers. SiTime continues to expand its SAM and delivers higher performance levels to our automotive customers. We work with leading EV OEMs today to deliver autonomous driving innovations that are redefining how we drive, navigate, and experience our cars.”
