Working Principle

The 445C33B12M00000 crystal is a piezoelectric device, which consists of a body and electrodes. As an external force is applied to the crystal, it generates a voltage across the electrodes. Conversely, when a voltage is applied to the electrodes, the crystal body changes its shape. Together, these two processes of voltage to force and force to voltage conversion enable the crystal to act as an oscillator.

Oscillator

The most basic requirement for an oscillator is that of a resonant frequency. The frequency at which the crystal oscillates depends on its size and shape; this is known as the "series resonance frequency". The crystal is cut to have a particular resonant frequency, which is typically measured in MHz. This resonant frequency determines the frequency of the oscillations produced in the oscillator circuit. The frequency can also be tuned slightly by changing the capacitance or inductance in the circuit.
