What Are Clock Oscillators?

The clock oscillator is manufactured by using the piezoelectric effect of the crystal. When an alternating voltage is applied to both sides of the wafer, the wafer will be repeatedly mechanically deformed to generate vibration, and this mechanical vibration will in turn generate an alternating voltage.

Clock oscillator

Right!

The clock oscillator is manufactured by using the piezoelectric effect of the crystal. When an alternating voltage is applied to both sides of the wafer, the wafer will be repeatedly mechanically deformed to generate vibration, and this mechanical vibration will in turn generate an alternating voltage.

An oscillator is a circuit that can generate an alternating current signal of a certain frequency.

A crystal oscillator, hereinafter referred to as a crystal oscillator, is manufactured using the piezoelectric effect of a crystal. When an alternating voltage is applied to both sides of a wafer, the wafer will repeatedly undergo mechanical deformation and vibrate, and this mechanical vibration will be reversed. Generate an alternating voltage. When the frequency of the applied alternating voltage is a certain value, the amplitude is significantly increased, and it is much larger than the amplitude at other frequencies, which generates resonance. This phenomenon is called piezoelectric resonance. The external oscillation circuit must be attached to the crystal. Generally, it is an amplified feedback circuit.Only a crystal can not achieve oscillation.

So there is a clock oscillator.The external clock circuit is placed in the same package as the crystal oscillator.Generally, there are 4 pins.The two power lines provide power for the clock circuit inside. A clock, or clock for short. Many clocks generally need to make some temperature compensation circuits in it to make the oscillation frequency more accurate.

The equivalent circuit of a crystal oscillator can also be considered as an LCR oscillator circuit.
