A circuit for producing an output signal having a transition between two states at a controlled phase displacement with respect to a transition between two states of a reference signal, comprising: means for deriving a phase command value representing a desired phase displacement between the transitions in the output signal and the reference signal; a counter coupled to the deriving means having a series of counter inputs that receive the phase command value, a load command input, a clock input and an output; means coupled to the load command input for causing the counter to load the phase command value at a time prior to the transition in the reference signal; a clock that develops a clock signal; a gating circuit having inputs that receive the clock signal and the reference signal and an output coupled to the clock input of the counter wherein the gating circuit provides a plurality of clock pulses to the clock input of the counter following the transition in the reference signal, the counter decrementing the loaded phase command value as clock pulses are received by the counter; and means coupled to the counter output for producing the output signal wherein the developing means produces the transition in the output signal when the loaded phase command value is decremented to a particular value.
