Wide Temperature TCXO

TKD Wide Temperature TCXO oscillators maintain temperature-compensated frequency stability across −40 °C to +105 °C, ideal for outdoor, automotive and industrial applications. Compact packages with CMOS or clipped-sine output deliver reliable timing in demanding environments.

Ranges of Wide Temperature TCXO

Engineered for extended thermal ranges, these TCXOs keep frequency drift tightly controlled from −40 °C to +105 °C while preserving low power. Standard packages and flexible output options support GPS, telematics and outdoor instrumentation designs.

Frequency Control Across Extended Temperature Conditions

Extended characterization

Each device is calibrated across −40 °C to +105 °C, so the compensation curve remains accurate even during rapid ambient swings common in outdoor gear.

Stability grades

Stability ±2.5 ppm across the extended range lets designers trade accuracy against cost for their specific environment.

Hysteresis control

Low thermal hysteresis keeps the output close to the calibrated curve during heating and cooling cycles, preserving system timing margins.

Thermal Design Considerations for Wide-Temperature TCXO

Thermal coupling

Mount the TCXO so its temperature sensor tracks the crystal temperature closely; avoid large heat sinks or airflow that create internal gradients and degrade compensation.

Placement

Keep the device away from hot power components and vents; moderate self-heating is acceptable if it stays within the characterized range.

Derating

For continuous high-temperature operation, verify the maximum operating temperature and current derating to ensure long-term reliability and stable frequency.
