Abstract
Systems, devices and methods are disclosed herein for reducing crosstalk between pairs of differential signal conductors. One or more ground traces connected to one or more over- or under-lying ground planes by vias are located between pairs of differential signal conductors. The electrical shielding provided by the combination of the one or more ground traces and the one or more ground planes results in reduced cross-talk between different pairs of differential signal conductors, and facilitates high-speed data rates between integrated circuits and printed circuit boards. In a preferred embodiment, such ground traces and ground planes are employed in HiTCE packaging containing multiple pairs of differential signal conductors.
