Abstract:
     The invention refers to a frequency divider that can be digitized operated and satisfies the Zigbee standard, as well as phase-locked loop which using this frequency divider. The frequency divider comprising several flip-latches of ring structure, output connection of back flip-latch to input of front latch. The frequency divider also comprising: import ends of clock end connected to latch together and used to receive frequency divided signal; as well as several output end connecting to the output end of flip-latch, used to outputting frequency-divided signal of different phase. The phase-locked loop of this invention having frequency divider, it using the frequency divider to frequency divides the 1/P and 1/P 0.5 of output frequency, consequently producing Zigbee channel frequency by 5MHz interval.
