Description

The model CO-770, low profile 4 Pin DIP Oven Controlled
Crystal Oscillator (OCXO) is available in frequencies from
10 kHz to 24 MHz with higher frequencies available to
80 MHz on special order.

This unit provides exceptionally low aging rates and
temperature stabilities in an extremely small package. It
measures only 0.50" x 0.80" x 0.35" (12.7mm x 20.3mm x

8.9mm); provides aging rates of <3 x 10
