1. A data processing system, the data processing system comprising:
a loop feedback circuit including:
an equalization circuit operable to equalize a data input to yield a equalizer output, wherein the equalization circuit includes:
a first phase equalizer circuit operable to equalize the data input to yield a first phase equalized output, wherein the first phase equalized output is offset from a defined phase by a first phase offset;a second phase equalizer circuit operable to equalize the data input to yield a second phase equalized output, wherein the second phase equalized output is offset from the defined phase by a second phase offset; anda selection circuit operable to select between at least one of a first output derived from the first phase equalized output or a second output derived from the second phase equalized output to be provided as the equalizer output; anda data detector circuit operable to apply a data detection algorithm to the equalizer output to yield a detected output.
