Abstract
A frequency generating device and an operation method thereof are provided. The frequency generating device includes an oscillator circuit and a processor circuit. The oscillator circuit generates a clock signal and adjust a clock frequency of the clock signal according to a control voltage generated by the processor circuit. The processor circuit calculates a current frequency aging rate value based on a current clock frequency. The processor circuit calculates a control voltage regulation rate value based on the current frequency aging rate value and a control voltage slope, and compensates the control voltage based on the control voltage regulation rate value in the holdover state. Alternatively, the processor circuit calculates a frequency regulation value based on the current frequency aging rate value and an oscillator resolution of the synchronizer, and provides the frequency regulation value to the synchronizer in the holdover state to compensate an output frequency of the synchronizer.
