Abstract
An electrical connector that includes a circuit board having a board substrate that has opposite board surfaces and a thickness measured along an orientation axis that extends between the opposite board surfaces. The circuit board has associated pairs of input and output terminals and signal traces that electrically connect the associated pairs of input and output terminals. The input and output terminals being configured to communicatively coupled to mating and cable conductors, respectively. Each associated pair of input and output terminals is electrically connected through a corresponding signal trace that has a conductive path extending along the board substrate between the corresponding input and output terminals. At least two signal traces form a broadside-coupling region in which the conductive paths of the at least two signal traces are stacked along the orientation axis and spaced apart through the thickness and extend parallel to each other for a crosstalk-reducing distance.
