Patent ID: 8094770

Claim:
A phase-locked loop comprising: (a) a sample selector configured to select a set of samples from an oversampled portion of a data signal; (b) a dynamic phase decision control circuit configured to indicate whether a predetermined number of edges is present in the set of samples; and (c) a phase detector configured to determine a skew condition and a direction of the skew condition of the set of samples based on the indication of the dynamic phase decision control circuit, wherein said phase detector is configured to produce a set of skew detection signals based on at least one skew condition determination, and wherein said phase-locked loop further comprises a loop filter configured to filter the set of skew detection signals, and wherein said loop filter is also configured to produce a set of phase adjustment signals based on the set of skew detection signals, and wherein said sample selector is configured to select a set of samples from the oversampled portion of the data signal, based on the set of phase adjustment signals.
