Abstract: Embodiments reduce crosstalk between electrical interconnects by offsetting pairs of electrical interconnects in an electrical system to produce a staggered interconnect pattern for which magnetic flux through a loop formed by a victim interconnect pair is effectively canceled. Magnetic field vectors generated by an aggressor pair of interconnects can pass through a loop-bounded surface defined by a victim pair of interconnects in the system. In the staggered interconnect pattern, the victim interconnect pair is offset with respect to the aggressor interconnect pair so that the field vectors passing through the victim pair's loop-bounded surface in one direction are substantially balanced by the field vectors passing through the victim pair's loop-bounded surface in the opposite direction, thereby minimizing the effect of the aggressor pair's magnetic field on the victim pair. Since crosstalk is proportional to the rate of change of the magnetic flux, reducing the magnetic flux can reduce the crosstalk.

Abstract: An electrical connector footprint on a printed circuit board (PCB) can include vias and antipads surrounding those vias. While conventional antipads surrounding vias are large in order to improve impedance of the PCB, the presence of the antipads can compromise the integrity of the ground plane and can permit cross talk to arise between differential pairs on different layers in the PCB. Antipads can be constructed and arranged so as to limit cross talk between layers in a PCB, while also maximizing impedance.
