Product Description

With CMOS output with exceptionally tight temperature stability, the HCD666 oven controlled oscillator provides an OCXO solution with extremely good ageing specifications and fast warm up time.

This oven controlled oscillator also features good close-in phase noise specifications, for example -150dBc/Hz @ 10Hz when operating at 5.0MHz, and a standard European pin out package which provides excellent protection for this high performance oven controlled oscillator, available at frequencies from 5.0MHz to 20.0MHz and with optional supply voltage.
