Abstract
A signal generator circuit includes an oscillator operative to generate a first signal having a first frequency associated therewith, and a phase stepper circuit coupled to the oscillator. The phase stepper circuit is configured to receive a plurality of control signals indicative of respective phases of the first signal, and to generate a second signal as a function of the plurality of control signals. The second signal has a second frequency associated therewith that is a fractional multiple or a fractional division of the first frequency. The second signal has a phase associated therewith which changes with periods of the second signal.
