Abstract
Data signal dropout may cause loss of synchronization between the data signal and a data clock. A dropout resistant system for generating the data clock synchronized to the data signal includes a phase-locked loop. The phase-locked loop outputs the data clock having frequency and phase based on phase difference between the data signal and the data clock. The phase-locked loop holds constant the data clock frequency and minimizes phase shift during periods when an indication of the data signal quality drops beneath a threshold level.
