FA-238 16.6666MB-C3 working principle

This crystal works on the principle of piezoelectricity. Applying an alternating electric field to a crystalline material causes it to vibrate at its mechanical resonance. Conversely, when a crystalline material is subjected to mechanical distortion, an associated electrical field will be generated. The frequency of the vibrations or "resonance" will depend upon the size and shape of the crystal. For example, a tiny quartz crystal can be made to vibrate at very high frequency.

In the case of FA-238 16.6666MB-C3 crystals, the 3.3V operating voltage is applied to the crystal to excite it, driving it to oscillate at its fundamental frequency. The output of the crystal then passes through a filtering circuit to produce a sine wave at the desired output frequency. The crystal is then connected to the device’s output circuit in order to supply a stable, precise frequency signal.
