锁相环
Phase-locked loop use external input reference signal control loop internal oscillation signal feedback control circuit. Digital phase locked loop frequency generator due to the frequency range and frequency interval can be adjusted according to the specific needs, and the output signal frequency with high stability and accuracy, and can be widely used as discrete signal source, can also be used for integration. In addition, if use single chip microcomputer to control the load end of the frequency divider, the adjustment of the frequency can be more easily.
