Abstract
A clock circuit for generating a spread spectrum clock signal with reduced amplitude electromagnetic interference (EMI) spectral components is provided where the clock circuit includes a delay line circuit, the delay line circuit providing a spread spectrum clock signal from a reference clock signal in response to a modulation signal, a delay of said delay line circuit being controlled by said modulation signal.
