Working Principle

The SIT9005ACU2H-XXDP programmable oscillator operates by modulating an external clock source in order to generate an output signal of adjustable frequency. The output signal is generated by a phase-locked loop circuit, which compares the phase of a reference signal (derived from the external clock source) with the phase of an electronic control signal. When the two signals are in phase, an output signal of the desired frequency is generated. The oscillator is programmed by an on-board microprocessor, which configures the parameters of the phase-locked loop circuit in order to generate an output signal of the desired frequency. The reference signal is generated by the external clock source, which feeds a low-power clock generator. This generates a low-power signal of a frequency equal to the frequency the external clock source. The reference signal is then phase-shifted based on user input, and then compared with the phase of the control signal. The output frequency is determined by the amount of phase-shift between the reference signal and the control signal. The user can adjust the output frequency by changing the configuration of the phase-locked loop.
