Working Principle

The initial source of quartz crystal oscillator is the piezoelectric effect. When mechanical strain is acted on quartz crystal, electric field will be generated on its surface and conversely, when electric field is generated, mechanical strain will be generated too.This phenomenon is called the piezoelectric effect. In the design of quartz crystal oscillator, two parallel pieces of quartz crystals are metallized together on one side so that when voltage is applied to the two parallel faces of one side and mechanical stressing is generated.

Quartz crystal oscillator can be regarded as a parallel combination electric circuit that consists of two capacitors C and Cc , a quartz crystal resonator R and inductor L together with other electrically conducting paths, capacitors, inductors and resistors, for completing the loop. When an electric field is applied on the two parallel faces of the quartz crystal resonator, mechanical stressing will be generated in the crystal lattice, electrical resonant frequency from the crystal lattice thus occur, resulting in a sustained oscillation with the identical initial frequency.
