As data rates increase, crosstalk becomes an increasingly important issue. Crosstalk aggressors can attack both amplitude and timing characteristics of the victim signal. There is relatively little understanding of how crosstalk affects the jitter of a victim signal because crosstalk does not fit neatly into the standard definitions of jitter components. As a result, most commercially available jitter analyzers misinterpret crosstalk. We investigate the effects of various types of crosstalk aggressors on a victim signal in an FPGA transceiver, with particular emphasis on jitter. We also demonstrate cases where crosstalk is misinterpreted as RJ, PJ, or ISI.
