OCXO - Oven Controlled Crystal Oscillators

OCXOs from Euroquartz  Oven Controlled Crystal Oscillators (OCXO) provide very high stability in quartz crystal-controlled oscillators. Any variation of output frequency, due to ambient temperature change, is minimized by placing the crystal in a thermostatically-controlled oven.
Oven controlled crystal oscillators manufactured by Euroquartz are designed to provide stabilities from ±0.02ppm over operating temperature range with AT-Cut crystals or ±0.005ppm using SC-Cut crystals. Most OCXOs may be specified with 5.0 Volts or 12.0 Volts supply.
