Abstract
A clock generator circuit for clock controlled electronic devices, which causes minimal electromagnetic interference in adjacent electronic equipment. The clock generator circuit includes a clock source for generating a basic clock signal having a predetermined frequency. The basic clock signal defines a reference clock signal having a period T. A phase modulator coupled to the clock source for producing a system clock signal by delaying the basic clock signal. A signal source coupled to the phase modulator, which controls the phase modulator so that the system clock signal is delayed with respect to the reference clock signal by a time period less than half of the period T of the reference clock signal.
