Precision timing specialist SiTime has unveiled the SiT1623/25 automotive-grade oscillators, designed to enable higher safety for advanced driver assistance systems, infotainment and car-to-home wireless connectivity. The new oscillators comply with the AEC-Q100 standard.
Precision timing is vital for all intelligent, connected automotive electronics, and SiTime believes that in 2018 approximately 20 timing chips were needed, compared to cars of today which require up to 60 timing chips. The company anticipates this number will continue to grow to 100 timing chips by 2026.
The company’s timing solutions are based on resilient and reliable silicon MEMS technology and have been developed to perform in harsh conditions to ensure they provide robust system performance and stability.
“This new generation of automotive oscillators is an additional milestone in the precision timing industry,” said Pierre Delbos, technology and market analyst, sensing and actuating, at Yole Intelligence, part of Yole Group.
“With the growing needs for high-frequency connectivity in cars and the inherent reliability of silicon-based oscillators, we expect the MEMS timing industry to grow with a 35% CAGR from 2021-2027.”
In addition to providing high performance in environments with high or low temperatures, or shock and vibrations, the SiT1623/25 devices also benefit from proven reliability and frequency stability over a wide temperature range. The solution has also been enhanced to deliver improvements in jitter and power consumption.
SiTime’s SiT1623/25 oscillators deliver a high-temperature, low-power timing reference for automotive connectivity protocols, including SerDes and automotive Ethernet. Automotive applications require high-speed in-car connectivity to transfer data between sensors, displays and central computers in the car. The new oscillators provide jitter performance and ±50 ppm frequency stability over -40oC to +125oC.
“Automotive is a dynamic market where electronics companies are innovating rapidly in the fields of automated driving, instrument clusters and connectivity. It is a focus market for SiTime, where we uniquely deliver superior robustness and reliability,” said Piyush Sevalia, executive vice president marketing, SiTime.
“The new automotive-grade SiT1623/25 oscillators are designed to perform in extreme conditions with exceptional stability and jitter, enabling safer cars with higher performance ADAS. Precision timing is the heartbeat of the latest automotive technologies that keep drivers safe and connected.”
