OCXOs and VCOCXOs provide an exceptional frequency stability by heating an SC-cut crystal and further package-internal circuitry to a single temperature, and keeping that temperature stabilized over a range of environmental temperature changes.
As this regulated and stabilized temperature is higher than the highest specified environmental temperature, the abbreviation OCXO stands for Oven Controlled Crystal Oscillator.
These OCXOs and VCOCXOs are an excellent choice if your application requires an extremely stable timing reference with part-per-billion frequency stability. Furthermore, key features are low phase noise, excellent short-term stability, low aging or low drift during holdover.
