A spread spectrum clock generator is disclosed. The spread spectrum clock generator (SSCG) bases on the structure of the phase-lock loop. The SSCG uses the voltage control oscillator with multi-phase output function for outputting clock signals of different phases. The clock signals of different phases are selectively fed back to the phase frequency detector. In this way, the frequency of the output signal is changed, which achieves spreading spectrum.
