CFV-20640000AZFB Working Principle

The oscillation frequency of the CFV-20640000AZFB is maintained by the applied voltage. The quartz crystal vibrates at a natural frequency of its own, called the resonant frequency. The applied voltage can vary the frequency of oscillation around its resonant frequency, enabling a signal frequency to be generated and then amplified.

The oscillation of the crystal is achieved due to the effect of the electrostatic force on the crystal lattice. The crystal is fixed between upper and lower electrodes, placed in an electric field that is constant or periodic. Each site in the crystal experiences forces resulting from the electric field, causing its lattice to vibrate at its resonant frequency, releasing energy in the form of small electric signals.
