摘要
A spread-spectrum clock generator (SSCG) and a spread-spectrum clock generating method are provided. The SSCG includes a first spread-spectrum module, a second spread-spectrum module, and a waveform module. The first spread-spectrum module generates a first spread-spectrum clock signal by modulating the frequency of a first input clock signal with a parallel delay configuration. The second spread-spectrum module generates a second spread-spectrum clock signal by modulating the frequency of a second input clock signal with the same parallel delay configuration. The waveform module is coupled to the first spread-spectrum module and the second spread-spectrum module for generating an output spread-spectrum clock signal according to the first and the second spread-spectrum clock signals.
