A 0.18/spl mu/m CMOS fully integrated 6.25Gbps single aggressor multi-rate crosstalk cancellation IC for legacy backplane and interconnect applications

A multi-rate crosstalk canceller for active cancellation of near end cross talk (NEXT) caused by a single aggressor in a backplane channel environment has been demonstrated in this paper. The proposed IC enhances the performance of existing legacy backplane at higher data rates, thereby avoiding the costs associated with upgrading to higher end backplanes and connectors. The IC has been fabricated in a 0.18/spl mu/m CMOS process and the prototype test bench demonstrated capability of improving the bit-error rate (BER) performance in excess of 5 orders of magnitude at data rates up to 6.25Gbps.
