A delay balancing circuit includes a phase detection circuit, a controller, and a delay circuit. The phase detection circuit receives a reference clock signal having a first frequency, and a feedback clock signal derived from an output clock signal. Detection circuitry detects a phase relationship between the reference clock signal and the feedback clock signal. The phase detection circuit generates a detection signal based on the detected phase relationship. The controller operates to sample the detection signal and to generate and pass an update signal to a delay line to update a delay based on the sampled value. The delay circuit receives a third clock signal and applies a delay, based on the update signal, to the third clock signal to generate the output clock signal.
