SiT8920: 1 to 110 MHz Ruggedized Oscillator for Harsh Environments

E-mail Print
4pin

The SiT8920 is the most robust and reliable oscillator on the market with 0.1 PPB/G vibration sensitivity (G-sensivity), 50kg shock and 70g vibration resistance and 500 million hour MTBF. In addition, this device delivers a perfect combination of high frequency (up to 110 MHz), best stability (±20 PPM), widest temperature range (-55 °C to 125°C ) and small packages (2.0 x 1.6 mmxmm) that are not available from quartz.

For the same device in a SOT23-5 package, refer to the SiT2020 clock generator.
