Title: Synthesizing Optimal Filters for Crosstalk-cancellation for High-Speed Buses Authors: Jihong Ren and Mark Greenstreet Where: DAC'2003 Abstract: We present practical algorithms for the synthesis of crosstalk cancelling equalizing filters. We examine designs optimized for the traditional $l_2$ metric and introduce an approach based on the $l_\infty$ metric. We compare the two approaches for realistic buses with tight wire spacings. We show bandwidth improvements of up to a factor of 2 using crosstalk cancellation when compared with no filtering or independent pre-emphasis for each wire. Using $l_\infty$ optimization, we achieve roughly 50\% better performance than the $l_2$ methods. We are aware of only one other published description of crosstalk cancellation for high-performance buses~\cite{Zerbe01}. We believe that our work is the first to show the advantages of $l_\infty$ optimization and to consider crosstalk cancellation for more than just nearest neighbours for high-speed buses.
