Product Description

Featuring fast warm up time and tight frequency stability of ±3.0ppm maximum over 10 years, the MCOCXOW is available at frequencies from 10.0kHz ~ 54.0MHz.

The MCOCXOW also offers three package options of surface mount or 14-pin DIL packages, requires 3.3V supply voltage, and is ideal for applications requiring tight stability, good shock and vibration tolerance combined with CMOS output.
