SiTime EnduraTM SiT8944 oscillators are suitable for high-reliability aerospace and defence applications.
Delivering a 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, 10,000g shock, and 70g vibration resistance.
As example of this would be the SIT8944BM-12-33EA25.000000, 25 MHz oscillator with +/-25 ppm stability over a temperature range of -55 to 125 degrees C.
