A circuit includes phase detection circuitry, a clock signal generation circuit, a first frequency divider, and a second frequency divider. The phase detection circuitry compares an input clock signal to a feedback signal to generate a control signal. The clock signal generation circuit generates a periodic output signal in response to the control signal. The first frequency divider divides a frequency of the periodic output signal by a first value to generate a first frequency divided signal. The second frequency divider divides the frequency of the periodic output signal by a second value to generate a second frequency divided signal. The first and the second frequency divided signals are routed to the phase detection circuitry as the feedback signal during different time intervals.
