The SiT8944 is a military-standard oscillator that enables the highest reliability and quality for extended temperature range (-55°C to 125°C). Due to its harsh environments resistance, this oscillator becomes a perfect choice for high-reliability aerospace and defense applications providing ultra-low 0.1 ppb/g acceleration sensitivity, 10,000 g shock, and 70 g vibration resistance. This Endura™ family oscillator delivers the perfect combination of the high-frequency range (1 to 110 MHz), excellent stability (±20 ppm), and wide temperature range (-55°C to 125°C) in the smallest 2.0 x 1.6 mm package that is not readily available from quartz suppliers.
