Quartz Crystal Oscillator Application In Our Daily Life

Mar. 14, 2018

The quartz crystal oscillator is a high-precision and high-stability oscillator, which is widely used in various types of oscillation circuits such as color TVs, computers, and remote controllers, as well as frequency generators in communication systems and clocks for data processing equipment. Signal and provide a reference signal for a specific system.

Quartz Crystal Oscillator

A quartz crystal oscillator is a kind of resonant device made by utilizing the piezoelectric effect of a quartz crystal. Its basic structure is roughly: cutting a thin piece of a quartz crystal at a certain azimuth and coating silver on its two corresponding surfaces. The layer serves as an electrode, and each lead is welded to a pin on each electrode, and a packaged case constitutes a quartz crystal resonator, which is abbreviated as a quartz crystal or a crystal and a crystal. Its products are generally packaged in metal enclosures and are also available in glass, ceramic or plastic packages.

There are four types of quartz crystal oscillators: ordinary crystal oscillator (SPXO), voltage-controlled crystal oscillator (VCXO), temperature-compensated crystal oscillator (TCXO), and temperature-controlled crystal oscillator (OCXO). The current development is also digital compensated crystal loss oscillator (DCXO) computer-compensated crystal oscillator (MCXO) and so on.
