Automotive & Ruggedized Oscillator Families

SiTime Automotive and Ruggedized Oscillator Families are designed for harsh-environment and high-reliability timing. These devices address timing requirements with the SiT8924 AEC-Q100 oscillator, the SiT8918 high-temperature oscillator, the Endura™ SiT8944 ruggedized oscillator, and the Endura™ SiT5346 ruggedized Super-TCXOs. The SiT8924 and SiT8918 target automotive and high-temperature environments, while the SiT8944 and SiT5346 undergo 100% Endura™ process screening for aerospace, defense, and high-reliability systems. All four devices support factory programmability across frequency, supply voltage, and stability grade. These devices are available in five industry-standard packages and function as drop-in replacements for quartz oscillators, requiring no board redesign. Typical applications include automotive, aerospace, defense, smart meters, airborne communications, avionics, infotainment systems, ADAS systems, automotive cameras, LiDAR, radar, automotive Ethernet, powertrain systems, and industrial systems.
