ClockOscillators:
A crystal oscillator, which consists of a crystal units and an inverting amplifier, outputs a stable frequency when subjected to a specific voltage. Crystal oscillators are employeed as a simple means of providing clock generators used for information processing in office automation and other electronic equipment.

Temperature Compensated Crystal Oscillators:
A temperature compensated crystal oscillators, or TCXO, compensates frequency-temperature characteristics of crystal units using a temperature compensation circuit, to give a highly stable output frequency. They are mainly used as reference signal sources in radio frequency circuits of cellular phones.

Voltage Controlled Crystal Oscillators:
Oscillators in which output frequency can be varied using an external control voltage.

Digital Temperature Compensated Crystal Oscillators:
Oscillators in which the voltage applied to a VCXO is controlled using a voltage control circuit and temperature is digitally compensated to give high stability of oscillation frequency.

Oven Temperature Compensated Crystal Oscillators:
Oscillators in which the temperature of components with a major impact on temperature is controlled by a constant temperature oven to give high stability of oscillation frequency.
