SiTime’s Automotive MEMS Oscillators Deliver 30 Times Better Robustness

330

SiTime, the leader in MEMS-based timing solutions and a wholly owned subsidiary of MegaChips Corporation today introduced two families of ultra-robust AEC-Q100-qualified MEMS oscillators.

AEC-Q100

The SiT2024/25 and SiT8924/25 oscillators deliver the highest performance and best robustness and are designed for ASIL (Automotive Safety Integrity Level) compliant automotive applications such as advanced driver assistance systems (ADAS), in-vehicle Ethernet, powertrain and electronic control units (ECUs).

“The automotive industry is going through a massive transformation, with new features such as advanced safety and driver assistance systems, electrification, automation and real-time big data analytics. The usage of electronic components in automobiles is increasing rapidly and requires stringent levels of quality, reliability and performance,” said Piyush Sevalia, executive vice president of marketing at SiTime. “MEMS technologies are playing a significant role in this transformation. SiTime is leveraging our revolutionary silicon MEMS, advanced analog technology and standard semiconductor packaging to provide unique timing solutions that deliver the highest reliability and dynamic performance under extreme temperatures, shock and vibration.”

SiTime’s new automotive product families offer a unique combination of the widest frequency range, tightest stability at ±20 ppm and the best reliability. The SiT2024/25 oscillators are optimized for under-the-hood systems such as engine control, transmission control, active suspension control, electronic steering and other ECUs.

These oscillators are available in a SOT23-5 leaded package to enable visual inspection and the best solder joint reliability, especially in hot and cold environments. The SiT8924/25 oscillators, available in industry-standard QFN footprints as small as 2.0 x 1.6 mm, are ideal for camera modules and other small form factor systems.
