Oven Controlled XTAL Oscillators

OCXO

In an OCXO, the crystal and other temperature sensitive components are placed in an ovenized enclosure where a temperature sensor, a heating element, and the oven control circuitry provide a temperature stabilized environment, thus isolating the crystal from external temperature variations. Keeping the crystal at a constant temperature greatly improves the oscillator performance and frequency accuracy.
