Abstract
Apparatus for clock synchronization comprising a first phase locked loop () and a second phase locked loop (). The first phase locked loop () is configured to receive a reference signal (Fcrystal) having a reference frequency, and operable to produce an output signal (Fout) having an output frequency that is a multiple of the reference frequency. The first phase locked loop () comprises a frequency divider () that controls the multiple in response to a control signal. The second phase locked loop () is configured to determine a phase error between the output signal (Fout) and an input signal (Fantenna), and to provide the control signal to the first phase locked loop (). The second phase locked loop () comprises phase adjustment means (), operable to adjust a phase difference between the input and output signal by varying the control signal for a duration.
