A phase-locked loop with a non-integer divider utilizes a state machine to periodically select a new clock from a plurality of clocks for comparison to a reference signal after division by an integer divide by N block. Based on a desired divider ratio, the state machine selects the new clock that is phase shifted with respect to a presently selected clock. Each change from the presently selected clock to the new clock produces a selected clock cycle that is expanded or contracted by the amount of phase shift between the new clock and the presently selected clock. The integer divide by N block divides the selected clock by the integer portion of the desired divider ratio producing a divided clock that is effectively divided by a non-integer amount.
