Abstract: A communication connector is described that includes a plug and a jack, into which the plug is inserted. The plug terminates a length of twisted pair cable. The jack includes a sled to support contacts for connecting to wires within the cable, a rigid circuit board that connects to the contacts, and a flex board that contacts the plug interface contacts. The jack also includes circuitry to compensate for crosstalk between wire pairs of the cable by adding capacitance values within the sled, rigid circuit board and/or flex board between traces carrying signals from the wire pairs so that crosstalk caused by the plug between wire pairs that have signals in phase cancels with crosstalk caused by the plug between signals out of phase, and so that the capacitance values added between each trace are about equal. The compensation is performed to reduce differential to common mode signal conversion.
