Controlled Oscillators

Controlled Oscillator is an oscillator device in which output frequency is proportional to its input. Based on the type of signal applied at input, there are different types of controlled oscillators available such as TCXO (Temperature Compensated Crystal Oscillators), OCXO (Oven Controlled Crystal Oscillators), VCXO (Voltage Controlled Crystal Oscillators), DCXO (Digitally Compensated Crystal Oscillators) and others.
