Abstract
An example clock synthesizer, having a single-phase clock signal as input and generating an output clock, includes a phase decrementer configured to receive a fractional period value, configured to, responsive to the fractional period value, maintain a fractional count, and configured to accumulate residual phase from cycle-to-cycle of the output clock. A clock generator provides an integer-count-zero signal indicative of an integer portion of the fractional count reaching zero. A clock phase selector is configured to provide a signal having a fractional portion of the fractional count. A phase generator and combiner is coupled to an output of the clock generator, and an output of the clock phase selector, and is configured to provide the output clock.
