A phase locked loop with phase clipping and/or resynchronization is disclosed. A reference signal is compared to a feedback signal derived at least in part from an output signal of an oscillator to determine a phase error. A magnitude of at least one of the phase error and a change in the phase error, if required, is clipped to provide at least one of a clipped phase error that has a clipped magnitude that does not exceed a prescribed maximum phase error and a clipped change in phase error that has a clipped magnitude that does not exceed a prescribed maximum change in phase error. If a resynchronization triggering event is detected, the oscillator is resynchronized with the reference signal. |
