    摘要: An electronic system having a spread spectrum clock. A spread spectrum clock source creates and transmits both a spread spectrum clock signal and a modulation signal. A spread spectrum clock generator uses a modulation waveform on the modulation signal to frequency modulate a reference oscillator frequency. A logic unit comprises a Phase Locked Loop that receives the spread spectrum clock signal and the modulation signal and generates a logic unit clock signal.
