Working Principle

A crystal oscillator is an electronic circuit that provides an electrical signal of precise frequency and very low power consumption. It is composed of a quartz crystal, an amplifier, and an oscillator circuit. The crystal is the heart of the oscillator. When voltage is applied to it, the crystal produces mechanical vibrations in a very narrow frequency range. When the amplifier converts those vibrations into electrical signals, the oscillator circuit helps them to maintain a stable frequency. By adjusting the properties of the crystal, the exact frequency of the electrical signals can be controlled.
