Abstract
A direct digital frequency synthesizer includes inputs for a reference clock signal and a control word, and an output for a synthesized clock signal. A phase accumulator coupled to the input for the control word and the reference clock signal has an output for a phase control signal. A phase shifter has inputs for the reference clock signal and the phase control signal and an output coupled to the output for the synthesized clock signal. The control word can be used to adjust the output frequency and phase of the synthesized clock signal.
