Patent ID: 8050317

Claim:
An equalizing method adapted for use in a receiver incorporating an adaptive equalizer, the method comprising: equalizing received serial data in the adaptive equalizer by first sampling the equalized serial data in synchronization with at least one of a plurality of recovery clocks having respectively different phases, wherein the plurality of recovery clocks are recovered from the equalized serial data, and shifting the at least one of the plurality of recovery clocks within a predetermined phase range in synchronization with at least one shift phase clock to perform a second sampling of the equalized serial data; measuring a size of an eye pattern associated with the equalized serial data and generating a corresponding eye pattern signal comparing the first sampling with the second sampling and calculating a corresponding number of errors, wherein the measured size of the eye pattern is determined in relation to the calculated number of errors and the eye pattern signal indicates the corresponding calculated number of errors; detecting an error in the equalized serial data and providing a corresponding error detection; adjusting an equalizing strength provided by the adaptive equalizer to the received serial data in relation to the eye pattern signal; and following adjustment of the equalizing strength, determining a reset condition for the adaptive equalizer in relation to the error detection.
