119 to 137 MHz, Wide Temperature Oscillator
LoginThe SiT8921B is the most robust and reliable high-frequency oscillator on the market with 0.1 ppb/g vibration sensitivity (g-sensitivity), 50,000 g shock and 70 g vibration resistance and 500 million hour MTBF. This device delivers a perfect combination of high frequency (up to 137 MHz), best stability (±20 ppm), military temperature (-55 °C to 125 °C) and smallest package (2.0 x 1.6 mm) that are not available from quartz.
For the same device in a SOT23-5 package, refer to the SiT2021B.
