An Oven Controlled Crystal Oscillator (OCXO) is an oscillator operated inside a temperature controlled oven which keeps the crystal and the oscillator circuit at a constant temperature.  The overall stability of OCXOs is far superior to that of other crystal oscillators. OCXOs are widely used in telecommunications, satellite, broadcast and other professional applications.

Golledge offers a comprehensive range of OCXOs from leading manufacturers in the industry.
