Abstract:
    This invention discloses a clock generation device based on a phase-locking ring including a crystal oscillator, a first phase-lock ring and a digital clock frequency divider characterizing in also including a clock frequency process unit, the clock signals output by said crystal oscillator pass through the first phase locking ring to be input into said clock frequency process unit, which regulates the frequency sphere of the clock signals output by the first phase-locking ring based on said clock frequency, then multiple digital dividers divide the output signals of the first phase-locking ring and the clock signals to get the clock of necessary frequencies.
