Abstract

A method for generating spread-spectrum synchronous clock signals includes comparing an input signal of a first frequency with a feedback signal of a second frequency in a loop of feedback; generating a first control signal and a second control signal; determining an integer part I of a control word F to track the first frequency; registering n levels for the first control signal and the second control signal to introduce n phase delays for randomly changing a fraction part r (0<r<1) of the control word F to provide a broadened boundary in frequency spectrum; and generating a synthesized periodic signal with the second frequency based on a base time unit Δ, the first frequency, and the control word F, the synthesized periodic signal being fed back as the feedback signal in the loop of feedback and outputted with the second frequency being locked within the broadened boundary.
