METHOD AND APPARATUS TO REDUCE THE EFFECT OF CROSSTALK IN A COMMUNICATIONS INTERFACE

摘要

A technique for reducing crosstalk between communications paths includes scrambling data using scrambling functions that reduce or substantially minimizing a probability that worst-case data patterns occur on communications paths adjacent to a potential victim communications path. In at least one embodiment of the invention, a method includes scrambling a plurality of data bits based at least in part on respective ones of a plurality of distinct combinations of one or more taps of a linear feedback shift register (LFSR). The plurality of data bits are scrambled for transmission during a first bit-time on corresponding ones of a plurality of adjacent communications paths.
