Ruggedised One-output Clock Generator, High-frequency

Manufacturer's part number :


Manufacturer SiTime


Description :

The SiT2021B is the most robust and reliable high frequency, single-chip, one-output clock generator on the market with 0.1 PPB/G vibration sensitivity (G-sensivity), 50kg shock and 70g vibration resistance and 500 million hour MTBF. This device delivers the most uncomprising combination of high frequecny (up to 137 MHz), best stability (±20 PPM) and widest temperature range (-55°C to 125°C). It comes in a 5-pin, small SOT23 pacakge that offers the best board level solder joint reliability and enables low cost, optical-ONLY board level inspection.
