SiTime Expands Addressable Market with its New Precision Timing Solution for Autonomous Vehicles
New Differential Oscillators Deliver 10x Higher Resilience and Reliability to Enable Level 4 and 5 Advanced Driver Assistance Systems (ADAS)
“Indeed, the market for radar, camera, LiDAR, and computing for ADAS is accelerating very fast,” reports
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
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
