SPREAD SPECTRUM CLOCK GENERATOR AND METHOD FOR GENERATING SPREAD SPECTRUM CLOCK SIGNAL

摘要

A spread spectrum clock generator for generating a spread spectrum clock signal is provided. The spread spectrum clock generator includes a phase-locked loop system and a random walk modulator. The random walk modulator generates a modulating signal according to a random walk model. Then, the phase-locked loop system generates a clock signal with spread spectrum in response to the modulating signal. A method for generating the spread spectrum clock signal using the spread spectrum clock generator is also provided.
