Standard OCXO

TKD Standard OCXO oscillators use an internal oven to hold the crystal at a stable temperature, delivering exceptional frequency stability for precision applications. Available in standard packages with stability to ±0.01 ppm, they serve telecom, GNSS and test equipment.

Ranges of Standard OCXO

Oven-controlled construction locks the crystal temperature, achieving parts-per-billion stability and low aging. Standard packages suit base stations, sync systems, GNSS receivers and calibration instruments that need a dependable precision reference.

How Oven Control Stabilizes Standard OCXO Frequency

Oven principle

A heater and control loop hold the crystal near its turnover temperature, where frequency is least sensitive to ambient change.

Stability gain

Oven control reduces temperature-induced drift to ppb levels, far beyond uncompensated or TCXO performance.

Warm-up behavior

The oven takes time to reach setpoint; stability specifications apply after warm-up, so systems should account for this during initial power-on.

Warm-Up, Power and Integration Considerations for Standard OCXO

Warm-up time

Plan for the specified warm-up time before accuracy is reached; keep the OCXO powered to maintain the oven temperature in timing-critical applications.

Power budget

The oven heater adds steady-state and start-up current; size the power supply accordingly, especially in battery-backed designs.

Thermal isolation

Allow airflow and spacing around the OCXO, and avoid nearby heat sources, so the oven does not have to fight large thermal loads.
