Manpack military radio in desert

Oscillators that work in the lab and in the field

SiTime Endura™ ruggedized timing devices are based on proven silicon MEMS technology. Compared to standard commercial quartz devices, they deliver shock survivability of 30,000 g, seven times better g-sensitivity, 20 times better reliability, and an order of magnitude better aging performance. Endura oscillators offer a range of factory-programmable features including programmable frequency to deliver the device you need with short lead times and without the expense of custom oscillators.
