Working Principle of CM309E19660800BCKT Crystal Oscillators

The CM309E19660800BCKT crystal oscillator works on the principle of piezoelectricity. A crystal composed of lead zinc niobium (PZN) material is coupled with piezoelectric electrodes, so that when a voltage is applied in the form of a sinusoidal wave, the material undergoes a mechanical strain and causes the crystal to vibrate. This vibration generates a signal that is directed back to the electrodes. The resulting high-frequency sine wave signal is used as the oscillator\'s output. The frequency of the signal is determined by the size and shape of the crystal and the capacitive load applied at the electrodes. The magnitude of the load determines the oscillation amplitude, while the frequency can be adjusted by “tearing” or “pulling” the crystal to change its shape. The CM309E19660800BCKT crystal oscillator maintains a high level of frequency stability over a wide temperature range, making it ideal for use in applications that require exact frequency control.

Conclusion

The CM309E19660800BCKT crystal oscillator is an affordable, compact and high-performance oscillator which is used in many different applications that require precise frequency control. It uses the principle of piezoelectricity to generate a high-frequency signal which is used as the oscillator’s output.
