Abstract
A method for generating spread spectrum clock signals having harmonic emission suppressions is disclosed. A set of delayed clock signals is initially generated by delaying a high-speed clock signal via a set of delay modules. Then, the leading edge of a first one of the delayed clock signals is selectively combined with a trailing edge of any one of the delayed clock signals to form a half-period spread spectrum clock signal having low harmonic emissions.
