Abstract:
A system and method for Feed Forward Equalizer (FFE)-Aided Clock Data Recovery (CDR) to calibrate phase offset and enhance gain in baud rate sampling phase detector is provided. In an embodiment, a clock data recovery (CDR) apparatus includes an incremental feed forward equalizer (INC-FFE) in a CDR path and a calibration component in an equalization path, the calibration component connected to the INC-FFE, the calibration component configured to adjust FFE coefficients for the INC-FFE according to a phase code (PC) index in a PC index table and one of a signal-to-noise-ratio (SNR) and a bit error rate (BER) of a sampled signal, wherein the PC index table comprises adjustment values for the FFE coefficients, and wherein the PC index is linearly related to a sampling phase.

Claim (Index 19):
The network component of  claim 15 , wherein the PC index table comprises a plurality of PC index tables and wherein the programming further comprises instructions to:\n determine one of a SNR and a BER for a plurality of entries in the plurality of PC index tables; and determine adjustments to the FFE coefficients according to the entries in the PC index from the PC index table that produces the best one of the SNR and the BER.
