A Crystal Oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to generate an electrical signal with an accurate frequency. It also has automatic amplitude control and frequency drift is very low due to temperature changes. Crystal Oscillators are only suitable for high-frequency applications. Crystal oscillator works on the principle of the Inverse Piezoelectric Effect, the applied electrical field will generate a mechanical distortion across some material. Therefore, it utilizes the vibrating crystal’s mechanical resonance, made through a piezoelectric material for generating an electrical signal of a certain frequency. Almost all microcontrollers have external oscillators when you want to use different clock speeds in the microcontroller itself. Crystal Oscillators have two leads, there is no polarity for crystals and hence, they can be connected in both directions.
