A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design of a decision feedback equalizer (DFE) Clock-And-Data Recovery (CDR) architecture that utilizes/produces one sample-per-bit in the receiver and reduces bit-error-rate (BER) is provided. The design generally includes a receiver circuit. The receiver circuit generally includes a decision feedback equalizer (DFE) that produces one sample per bit, and means for automatically self-adjusting the DFE to enable an eye centering process by which peak energy is maintained within the receiver circuit when phase error is a minimum.
