Standard TCXO

TKD Standard TCXO oscillators combine a quartz resonator with temperature compensation circuitry to deliver stable frequency over temperature. Offering ±2.5 ppm stability in compact 1612–3225 packages, they are ideal for GPS, telecom and precision instrumentation.

Ranges of Standard TCXO

Each series delivers temperature-compensated frequency stability in standard ceramic packages with CMOS or clipped-sine output. Compact sizes, tight stability and low power make them a trusted timing source for wireless modules, base stations and test equipment.

Temperature Compensation and Frequency Accuracy in Standard TCXO

Compensation principle

A temperature sensor and compensation network correct the crystal's natural frequency drift, holding output ±2.5 ppm across the rated range.

Accuracy contributors

Initial calibration, temperature hysteresis and aging all add to frequency error; standard TCXOs balance these to meet GPS and telecom holdover needs.

Calibration

Factory trimming at multiple temperature points ensures the compensation curve matches each device, giving consistent, repeatable accuracy from unit to unit.

Key Electrical Parameters for Standard TCXO Integration

Frequency stability

Check the stability grade and operating temperature range against the system budget; tighter grades cost more but save margin in multi-constellation GNSS and small-cell designs.

Supply and current

Confirm the operating voltage (3.3 V or 5 V typical) and current consumption, especially for battery-powered wireless modules where power is critical.

Output type

Choose CMOS for digital loads or clipped-sine for RF front-ends, and verify the load and coupling requirement so the signal level matches the receiver input.
