Crystal Resonator
Crystal Resonator
Quartz crystal, or just known as crystal, is an importantpiezoelectric material. Its constituent atoms or molecules are packed in aregularly ordered, repeating pattern. Externally, this is reflected by thesymmetry of the shape. Underthe function of an electric field, the crystal will generate stress internallyand be distorted, and then produce mechanical vibration to obtain a specificfrequency. The crystal resonator is made using this inverse piezoelectriceffect. As quartz has natural high Q factor, the crystal resonator can maintainhigh precision and frequency stability within the whole temperature range andvoltage range.
