What is a voltage controlled temperature compensated crystal oscillator?

Temperature Compensated Crystal Oscillators (TCXOs) deliver excellent temperature characteristics combined with low power consumption and fast warmup. Voltage Controlled Temperature Compensated Crystal Oscillators (VC-TCXOs) combine the same excellent temperature characteristics, low power consumption and fast warmup with a voltage control function to allow precise tuning of the output frequency after PCB assembly.

Voltage control can also be used during operational life, to compensate for any effects of aging as well as offering the ability to pull back to nominal frequency where there is a change of circuit conditions. TCXOs and VC-TCXOs are used where the stability of a standard Crystal Clock Oscillator is insufficient.
