Working Principle

The SIT9120AI-1D2-25E166.666660X oscillator consists of a quartz crystal resonator, an amplifier, and an output stage. The crystal resonator is usually made from quartz, which is an electrical insulator with piezoelectric properties. By applying an electric field, the crystal can produce a small mechanical vibration at a specific frequency determined by its physical shape and the type of crystal. This "tuned" vibration is then amplified by the amplifier and passed through the output stage, which forms an oscillating sine wave.

The oscillator is able to sustain a constant frequency by providing feedback to the amplifier. When the output signal deviates from the profile of the sine wave, the amplifier increases its gain until the output signal is brought back into the desired shape. This constant feedback loop is known as negative feedback, and it ensures that the oscillator is able to maintain a consistent output frequency.
