An apparatus includes a processor, a clock recovery circuit and a frequency locked loop. The processor receives a system clock signal to clock operations of the processor; and the clock recovery circuit recovers a clock signal from data communication occurring over a bus. The frequency locked loop receives the clock signal from the clock recovery circuit as a reference clock signal, and the frequency locked loop is adapted to lock onto the clock signal provided by the clock recovery circuit to provide the system clock signal.
