Quartz crystal oscillator, is a high-precision and high-stability oscillator, can be used in a full range of color TV, computer, remote control and other types of oscillation circuit, can also be used in communication systems for frequency generators, for data processing equipment to generate clock signals and provide reference signals for specific systems. Why can the crystal oscillator achieve these effects? This is also there is a certain working principle, the following to understand the details.



Quartz crystal oscillator through the piezoelectric effect of quartz crystal, that is, silicon dioxide crystal to obtain a resonant device, its basic composition can be seen as from a quartz crystal according to a certain azimuth Angle cut thin, that is, wafer, the shape can be square, rectangular or circular, etc., in its two corresponding surfaces coated with silver layer as electrode, Each electrode is welded with a lead wire connected to the pin, and the packaging shell constitutes a quartz crystal resonator, which is what we call quartz crystal or crystal and crystal oscillator. Its products are usually packaged in metal shell, and some are packaged in glass shell, ceramic or plastic.



In general, quartz crystal oscillator can achieve a lot of functions, through the introduction of the above working principle, we also hope that you can have a deeper understanding of the crystal oscillator, so that you can make better use of the crystal oscillator and achieve more functions
