Working Principle

The working principle of the KC2520K33.3333C10E00 oscillator is based on the fact that a quartz crystal vibrates at its natural resonance frequency when an electrical voltage is applied to it. This resonance frequency is determined by the size, shape and cut of the crystal and can easily be varied by adjusting the electrical parameters. The crystal is connected to an amplifier, in this case a JFET (Junction Field Effect Transistor) amplifier, which amplifies the output signal from the crystal and passes it through a resonant tank circuit, consisting of inductors and capacitors, to produce a resonant output.

The resonant output frequency from the tank circuit is then fed to a comparator, which is typically a Schmitt trigger circuit, to produce a clean, low noise, digital square wave output. The resonant output frequency can be fine-tuned by adjusting the electrical parameters of the crystal, the inductors and capacitors of the tank circuit, and the threshold voltage of the comparator.
