Abstract
A method and apparatus for spread spectrum clock generation is provided. Modulation of the clock signal may be accomplished with an N/N−1 clock divider. The N/N−1 clock divider is configured to divide the clock signal by N or N−1, depending on the carry output signal of an accumulator circuit. The accumulator circuit is configured to provide the carry output signal in response to a modulating waveform signal. The modulating waveform signal may be a triangle wave, a sinusoidal wave, another waveform appropriate for spread-spectrum clock generation, and the like.
