Abstract
A digital spread spectrum clock generator. The generator includes a digital waveform generator adapted to generate a sequence of digital words representing a predetermined varying waveform, and an accumulator. The accumulator includes a first two input adder and a second two input adder, the second adder having its output stored and applied to a first input of the second adder. The first two input adder is adapted to receive at a first input a control word, to receive at a second input the sequence of digital words, and to provide a sum output which is provided to a second input of the second adder. One of the bits of the output of the second adder is usable as a spread spectrum clock, or it may be provided to a phase locked loop to reduce jitter.
