RFMW announces design and sales support for rugged, MEMS-based timing solutions from SiTime. SiTime Endura oscillators boast the highest robustness and reliability such as 0.004 ppb/g acceleration sensitivity, 30,000g shock, 70g vibration resistance, one billion hour MTBF and ±500 ppb 20 year aging. 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, Endura oscillators are ideal for high-reliability aerospace and defense applications such as munition guidance, vehicle comms/telemetry, command/control, avionics & drones, satellite GNSS and field communication systems. For example, the SiT5349, ultra-precision TCXO platform offers ±50 ppb stability over temperature with an operating temperature range of 0 to 70 degrees C and frequencies ranging from 60 to 220 MHz.
