Design and sales support for rugged, MEMS-based timing solutions from SiTime is now being offered by distributor RFMW.

SiTime Endura oscillators offer industry leading robustness and reliability with 0.004 ppb/g acceleration sensitivity, 30,000g shock, 70g vibration resistance, one billion hour MTBF and ±500 ppb 20 year ageing.

The Endura series includes single-ended and differential XOs, TCXOs and VCXOs.

Engineered for harsh environments and conforming with MIL-PRF-55310 and MIL-STD-883 specifications, the oscillators are suitable for high-reliability aerospace and defence applications such as munition guidance, vehicle communications/telemetry, command/control, avionics & drones, satellite GNSS and field communication systems.

For example, the SIT5346AICFQ-33N0A50.000000, super TCXO provides ±0.1ppm stability over a temperature range of -40 to 85 degrees C.
