  • Oversampling data recovery apparatus and method
    Patent number: 6611219
    Abstract: An open-loop data recovery apparatus and method utilizing an oversampling technique is provided, by which the occurrence of data transitions is counted and a proper sampling clock phase is decided. Counters with variable thresholds are used to monitor the occurrence of phase transitions for a phase selection circuit to determine a preferred phase for recovery of sampled data. The thresholds of the counters are further adjusted in reference with the preferred phase decided by the phase selection circuit.
