Abstract
A conductive area or layer of a circuit board is aligned with, and spaced from, a portion of a first differential signal conductor pair and connected through a conductive pathway to one of the conductors of a second differential signal conductor pair to provide capacitive coupling for compensating an imbalance arising from non-symmetric pin assignments. By compensating the imbalance, signal quality and/or immunity is improved and noise and/or emission is reduced.
