Abstract
The present invention is to provide a method and circuit for producing spread spectrum and over clock, which includes a primary circuit and a secondary circuit, wherein the primary circuit uses a frequency division technique based on phase swallow to achieve a high frequency resolution clock signal, and the secondary circuit multiplies the frequency of the output clock signal of the primary circuit, so as to expand its frequency range.
