Abstract:
A clock generating apparatus includes an oscillator and a frequency synthesizer. The oscillator is utilized for generating a reference clock signal. The frequency synthesizer is coupled to the oscillator and utilized for synthesizing a target clock signal in accordance with the reference clock signal and a frequency division factor that has been adjusted or compensated, and outputting the target clock signal as an output of the clock generating apparatus.
