Crystal Oscillator

 Clock Oscillator
Quartz crystal oscillators are made up of a crystal unit and an inverting amplifier, and emit a stable frequency when subjected to a specific voltage. Quartz crystal oscillators are a simple means of providing the clock generators used for information processing in office automation and other electronic equipment.

 Temperature Compensated Crystal Oscillator(TCXO)
A temperature compensated crystal oscillator or TCXO compensates the frequency-temperature characteristics of the crystal unit using a temperature compensation circuit, to give a highly stable output frequency. They are mainly used as reference signal sources in the radio frequency circuits of cellular phones.
