Product Description

The SCOCXOV oven controlled oscillator features CMOS output with very fast warm up time and ultra tight frequency stability of ±2.5ppm maximum over 10 years. This OCXO also features temperature stability options as tight as ±0.2ppm maximum over wide -55 to +85°C operating temperature range.

With supply voltage of 5.0V at frequencies from 10.0kHz ~ 54.0MHz, and optional surface mount or 14-pin DIL package, the SCOCXOV is ideal for applications requiring tight stability, excellent shock and vibration tolerance and low current consumption combined with CMOS output.

As a part of our product rationalisation the SCOCXOVT has been incorporated into the SCOCXOV family. Please speak to our team if you have any queries regarding existing documentation or if you would like more information about the SCOCXOV.
