Circuitry for delaying a signal includes a phase-locked loop comprising one or more output nodes for outputting one or more output signals in response to a reference signal. A buffer is coupled to the output nodes of the phase-locked loop for receiving phase-locked loop output signals and outputs one or more buffered output signals. A multiplexing element receives the buffered output signals and a control signal and generates an operative buffered output signal in response to the control signal. A delay line receives a delay control input signal and the operative buffered output signal from the multiplexing element. The delay line outputs a delayed output signal in response to the delay control input signal.
