SiTime Corporation announced its Endura Epoch Platform built for robust and resilient positioning, navigation and timing (PNT) services critical in defense operations. The ruggedized MEMS oven-controlled oscillator (OCXO) boosts the resilience of PNT systems and other equipment, such as radars, field and airborne radios, satcom terminals, and avionics against spoofing, jamming, and other disruptions in Global Positioning System (GPS) signals.
Based upon the transformative precision timing innovations of the Epoch Platform launched in September 2023, the Endura Epoch MEMS OCXOs are specifically designed to meet the challenging shock and vibration conditions found in aerospace and defense. These devices are manufactured using proven semiconductor processes that deliver the reliability and quality expected from silicon devices that cannot be achieved by quartz crystal OCXOs, especially in extreme conditions.
The Endura Epoch Platform MEMS OCXO greatly simplifies timing system design due to superior performance and delivers a significant improvement in size, weight, and power (SWaP). Key features and benefits compared to quartz crystal OCXOs include: Programmable frequencies from 10 to 220 MHz; Up to 70X better g-sensitivity; Up to 30X better reliability; Rated at 20,000 g shock survivability, up to 20X better; Up to 20X better frequency stability over temperature; Up to 3X better Allan deviation, a measure of short-term frequency stability; Surface-mountable, small footprint, and low height 9.0 mm x 7.0 mm x 3.6 mm; Low 0.35 g weight, up to 300X lower; 420 mW steady state power, up to 2X lower;
Endura Epoch Platform MEMS OCXO samples will be available for selected customers early in 2024.
