Working Principle

FA-20H 26.0000MF10V-K3 works on the same principle as other quartz crystal oscillators. Its working principle is based on the strong piezoelectric effect of crystal quartz.

When a voltage of the correct polarity is applied to the electrodes, the quartz crystal is deformed, generating a mechanical vibration. The vibration is synchronized to the applied electrical field in a process called either direct piezoelectric effect or inverse piezoelectric effect according to its physical geometry.

The vibration reaches its peak value when the frequency of the alternating current applied to the electrodes matches the resonant frequency of the crystal. This frequency generates an electromagnetic field of the same frequency. The output of the oscillator is then taken from a transformer which is wound around the crystal. Then, an AC voltage is produced from the transformer with the same frequency as the resonant frequency of the crystal.
