Working Principle

The working principle of the SIT9120AI-2B3-25E148.351648T oscillator is based on a voltage-controlled oscillator (VCO) circuit. The device consists of two main components: a star-shaped crystal resonator and a frequency-locking loop. The loop is responsible for providing feedback and comparing the actual frequency with the desired frequency, so that the oscillator output frequency stays within the given tolerance.

The oscillator works by varying the capacitance of the loop to control the frequency. This is achieved by applying a control voltage to the VCO, which then alters the capacitance. As such, the frequency of the output signal is determined by the applied control voltage. The resonator provides the required frequency stability over temperature and other environmental conditions.
