Temperature Compensated Crystal Oscillator(TCXO)
 |
RTx Technology offers standard and custom temperature compensated crystal oscillators (TCXOs).TCXOs offer excellent temperature characteristics with low power consumption and fast warm-up. TCXOs use special electronics to stabilize the output frequency as temperature changes.
TCXO, temperature compensated crystal oscillator, in which, e.g., the output signal from a temperature sensor (e.g., a thermistor) is used to generate a correction voltage that is applied to a variable reactance(e.g., a varactor) in the crystal network.
The reactance variations compensate for the crystal's f vs. T characteristic. Analog TCXOs can provide about a 20X improvement over the crystal's f vs. T variation.
