SiT5301: High Performance Stratum 3 MEMS VCTCXO

E-mail Print
4pin

The Stratum 3 compliant SiT5301, with its rich feature set, permits an unlimited number of oscillator configurations that are simply not available from legacy OCXOs and TCXOs. This device supports any combination of frequency (up to 60MHz with 6 decimal places of accuracy), voltage (2.5V-3.3V) and package (2520, 3225, 5032, 7050) along with large pull range (±12.5PPM), no Activity Dips and programmable rise/fall time control for better EMI. It provides superior shock and vibration resistance, and 2 FIT reliability that is 20 times better than quartz devices and is ideal for high reliability telecom and networking infrastructure applications
