Endura MEMS Oscillators for Aerospace and Defense

Endura MEMS SiT8944 Oscillators

September 29, 2021

RFMW announced design and sales support for rugged, MEMS-based timing solutions from SiTime. SiTime Endura SiT8944 oscillators are among the most reliable and highest quality oscillators for high reliability aerospace and defense applications. Delivering the perfect combination of wide frequency range (1 to 110 MHz), excellent stability (±20 ppm), and wide temperature range (-55 to 125°C) in the smallest 2.0 x 1.6 mm package that is not readily available from quartz suppliers. Engineered for harsh environments, this oscillator features ultra-low 0.1 ppb/g acceleration sensitivity, 10,000 g shock, and 70g vibration resistance.  An example of this would be SIT8944BM-12-33EA25.000000, 25 MHz oscillator with +/-25 ppm stability over a temperature range of -55°C to 125°C.
