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.
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.
TSX improves stability over plain crystals at a fraction of TCXO cost, ideal for volume products.
The embedded thermistor tracks crystal temperature directly, giving the compensation circuit accurate, fast thermal data.
With temperature known, a resistor network or simple analog loop can offset the crystal's frequency-temperature curve.
Verify the compensated frequency at key temperatures during prototyping to confirm the design meets the stability target.
Connect the thermistor terminals to the compensation network, keeping the sensing trace short and away from heat sources.
Size the resistor network so the correction tracks the crystal's curve across the operating temperature range.
