Abstract:
An apparatus includes a frequency locked loop and a controller. The controller stores a state of the frequency locked loop at which an output signal of the frequency locked loop is locked onto a reference signal and subsequently initializes the frequency locked loop with the stored state to cause the frequency locked loop to relock the output signal to the reference signal.
