Working Principle

Oscillators create a regular frequency signal by means of electronic circuitry, and their purpose is to provide regular timing signals so that computers, radios and other electronic devices can function properly. The SIT9120AC-1BF-33S75.000000G oscillator works in a similar way as other oscillators, but with some additional features. The oscillator comprises of a frequency control circuit, which includes crystal resonators, varactors, and capacitors; and a voltage controlled oscillator (VCO) that converts electrical signals to oscillating frequency. The frequency control circuit takes the frequency reference from the crystal resonators and then the required frequency is generated from the VCO. The generated frequency is then locked into a phase-locked loop (PLL) which is used to stabilize the generated frequency.
