Standard TSX Crystals | TKD

TKD Standard TSX crystals integrate a thermistor with the quartz resonator, enabling simple temperature compensation in crystal oscillator circuits. This cost-effective solution improves frequency stability for wireless modules, RTCs and industrial equipment.

Ranges of Standard TSX Crystals

Combining a quartz resonator with an integrated thermistor, these crystals provide temperature information for simple compensation circuits. They suit wireless modules, TCXO-like designs, meters and other applications needing improved stability.

How Thermistor Sensing Supports Frequency Compensation in TSX Crystals

Cost-effective stability

TSX improves stability over plain crystals at a fraction of TCXO cost, ideal for volume products.

Integrated sensing

The embedded thermistor tracks crystal temperature directly, giving the compensation circuit accurate, fast thermal data.

Simple compensation

With temperature known, a resistor network or simple analog loop can offset the crystal's frequency-temperature curve.

Electrical Integration Considerations for Standard TSX Crystals

Calibration

Verify the compensated frequency at key temperatures during prototyping to confirm the design meets the stability target.

Thermistor wiring

Connect the thermistor terminals to the compensation network, keeping the sensing trace short and away from heat sources.

Compensation design

Size the resistor network so the correction tracks the crystal's curve across the operating temperature range.
