Electrical connectors and printed circuits having broadside-coupling regions
First Claim
1. An electrical connector configured to communicate differential signals, the electrical connector comprising:
- mating conductors configured to engage contacts of another connector, the mating conductors comprising first and second differential pairs; and
a circuit board including a plurality of signal traces and a plurality of associated pairs of terminals, each of the associated pairs including an input terminal and an output terminal that are electrically connected through one of the signal traces of said plurality, the input terminals being electrically connected to corresponding mating conductors, each of the signal traces having a conductive path that is configured to transmit signal current between the associated input and output terminals, the signal traces including first and second signal traces that are associated with the first differential pair of signals and third and fourth signal traces that are associated with the second differential pair of signals;
wherein the first, second, and third signal traces are stacked and spaced apart from each other to form a broadside-coupling region, the first, second, and third signal traces extending parallel to one another through the broadside-coupling region for a crosstalk-reducing distance.

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.
