SiT8924B Automotive Grade Oscillators

SiTime's SiT8924B series of high reliability AEC-Q100 compliant oscillators are designed for extreme temperature applications

Image of SiTime's SiT8924B Automotive Grade OscillatorsThe SiT8924B series from SiTime Corporation offer highly reliable and high quality AEC-Q100 compliant oscillators for automotive and extreme temperature applications. This device provides a perfect combination of a wide frequency range (1 MHz to 110 MHz), excellent stability (as low as ±20 PPM), and a wide temperature range (-55°C to +125°C) in one of the smallest (2.0 mm x 1.6 mm) packages that is not readily available from quartz. It also features one of the industry's best shock and vibration resistances.

The SiT8924 is available in five industry standard packages, and therefore replaces quartz products without any design changes. SiTime's MEMS oscillator consists of a MEMS resonator and a programmable analog circuit. The SiT8924 MEMS oscillator is built with SiTime’s unique MEMS First™ process. A key manufacturing step is EpiSeal™ during which the MEMS resonator is annealed with temperatures over +1000°C. EpiSeal creates an extremely strong, clean vacuum chamber that encapsulates the MEMS resonator and ensures the best performance and reliability in harsh environments.
