Working Principle

The 445A22A27M00000 crystal oscillator is basically composed of a quartz crystal oscillator, a transistor pair stage, and a resonator. The quartz crystal oscillator has the Reactive Piezoelectric effect. When an AC signal is applied to the crystal, the crystal deforms and produces a voltage. Conversely, when a voltage is applied to the crystal, the crystal will deform and generate an AC signal. This deformation and voltage changes form a resonant system and a crystal oscillator.

The resonator in the oscillator divides the large capacitance for the crystal. Generally, it consists of a small capacitor and a resistor. This can reduce the load impedance of the crystal and ensure that the quarts crystal is in a better oscillator state. The transistor pair stage is used to amplify and stabilize the output frequency signal generated by the quartz crystal oscillator.
