Provided is an electrical connector that may reduce crosstalk between leadframe assemblies. Such a connector may have a connector housing, a first leadframe assembly contained in the housing, and a second leadframe assembly contained in the housing adjacent to the first leadframe assembly. The first leadframe assembly may have a first differential signal pair of electrically-conductive contacts. The second leadframe assembly may have a second differential signal pair of electrically-conductive contacts. Each contact of the first and second differential signal pairs may have a respective first portion, a second portion, and a third portion. Crosstalk generated on the second differential signal pair by a signal traveling through the first portions of the contacts of the first differential signal pair may be reduced by crosstalk generated on the second differential signal pair by the signal as it travels through the second portions of the contacts of the first differential signal pair.
