SIT8944

The Endura™ SiT8944 is the most reliable and the highest quality oscillator for high-reliability aerospace and defense applications. This device delivers the perfect combination of the 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. 

The MEMS-based Endura SiT8944 is 100% screened through the SiTime Endura™ process flow to provide high reliability.
