METHOD FOR REDUCING ELECTROMAGNETIC INTERFERENCE AND CLOCK MANAGEMENT CIRCUIT (COHERENT FREQUENCY CLOCK GENERATION AND SPECTRUM MANAGEMENT WITH NON-COHERENT PHASE)

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing electromagnetic interference in a clocked circuit.;SOLUTION: In the disclosed method, the clock circuit includes at least a first clock signal and a second clock signal. The method detects when a first transition of the first clock signal is substantially aligned with a corresponding second transition of the second clock signal. The method further delays the second clock signal by a predetermined amount of time when the first transition is substantially aligned with the second transition.;COPYRIGHT: (C)2008,JPO&INPIT
