AEC-Q100 automotive-grade Super-TCXO

Login

The SiT5186 AEC-Q100 automotive-grade Super-TCXO™ is a highly flexible, tight-stability oscillator for high-reliability systems in automotive. Based on the Elite Platform with SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, this device delivers excellent dynamic performance in the presence of common environmental hazards, such as airflow, temperature perturbation, vibration, shock, power supply noise, and electromagnetic interference (EMI).

The SiT5186 can be factory-programmed to any combination of frequency, stability, voltage, and pull range. This programmability enables designers to customize MEMS TCXO configuration for best system performance while eliminating the long lead time and customization costs associated with quartz devices.
