Endura™ Ruggedized Timing Solutions

SiTime Endura™ Ruggedized Timing Solutions for aerospace and defense are MEMS-based timing devices for mission-critical operations under shock, vibration, extreme temperature, and other harsh environmental conditions. These devices operate in a factory-programmable frequency range from 32.768kHz to 900MHz, as low as 0.004ppb/g typical acceleration sensitivity and a high reliability (>2.2 billion hours MTBF). The Endura™ supports multiple product families, including OCXOs, MHz Super-TCXOs, low-noise Super-TCXOs, differential oscillators, and kHz oscillators. These devices offer unchanged performance under random vibration, >100,000g shock survivability, semiconductor manufacturing quality, and 6-sigma processes. Typical applications include GNSS receivers, tactical communications, MOSA open architectures, UAVs and drones, LEO SatCom, vehicle communications, and pulse-per-second timekeeping.  

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.
