Abstract
A data recovery unit (DRU) includes: an oscillator; a phase detector unit configured to receive a reference phase and to receive input data through N wires, where N is an integer, to compare the reference phase with the input data to obtain phase errors, and to determine an average of the phase errors; a subtractor to subtract an output of the oscillator from the average of the phase errors to obtain an unbiased phase error; a delay unit to receive the input data; and a sample selector configured to receive an output from the delay unit and the output of the oscillator, and to output recovered data.
