Working Principle of FC-12M 32.7680KA-A5

The working principle of a quartz crystal can be understood in terms of simple harmonic oscillation. When a quartz crystal is subjected to an alternating electric field, electrical charges are distributed over the crystal in such a way that the electric field at any point in the crystal is having oscillatory components in the same direction as the applied field. If a large enough electric field is applied, multiple oscillations can occur over the crystal, resulting in an increase in frequency of the oscillation. This phenomenon is known as resonance and is the basis for the common Quartz crystal oscillators found in most electronic devices, the FC-12M 32.7680KA-A5 crystal included.
