ABSTRACT:
A device for reducing or eliminating differential mode cross-talk between data communication channels (CH1 and CH2) in a balanced communication system by coupling one or more auxiliary capacitances (C100) across the transmission lines (A, A, B, and B) between the two channels (CH1 and CH2), thereby augmenting the intrinsic capacitive couplings (CA.sub.AB, C.sub.AB, C.sub.BA, and C.sub.BA) and leakage between the channels in order to net the differential cross talk signal to zero.
