Abstract
Synchronization apparatus comprising a phase-locked loop for generating an output signal and for synchronizing the output signal to an input signal, characterized in that the apparatus comprises a controller for iteratively determining whether the output signal is synchronized to the input signal by the phase-locked loop and adjusting the frequency of the output signal to bring the output signal within the capture range of the phase-locked loop if the output signal is not synchronized to the input signal.
