What are Crystal Oscillators?

Oscillators are active devices that are the "source" of the radio frequency sine waves. Crystal oscillators operate by utilizing the piezoelectric properties of quartz. Quartz, by nature has a pressure-electric relationship, which means that the voltage and current are related to the displacement and mechanical stress on the crystal. Therefore, the frequency at which a crystal oscillates can be controlled by the voltage and current, making quartz a perfect candidate for RF generation.
