115至137 MHz，延长温度（-55°C至125°C）振荡器
The Endura™ SiT8945 is the most reliable and the highest quality oscillator for high-reliability aerospace and defense applications. This device delivers the perfect combination of high frequency range (up to 137 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, 10,000gshock, and 70gvibration resistance.
基于MEMS的Endura Si8945符合MIL-PRF-55310，MIL-STD-883和AEC-Q100规格。
