A signal cable for an AC-coupled link, may include: a signal conductor; a dielectric surrounding the signal conductor; and a ground sheath having a conductive layer disposed at least partially around the conductor such that the dielectric is positioned between the ground sheath and the signal conductor, wherein the conductive layer comprises a first portion extending in a first direction along the cable and a second portion extending in a second direction, opposite the first direction, along the cable and further wherein the first and second portions of the conductive layer are separated from each other by a gap, the gap being dimensioned to provide a determined amount of capacitance in series in the ground sheath. The gap may form a complete separation between the first and second portions of the conductive layer.

AC-coupling structure in electrical cabled interconnect

A multiple-layer circuit board has a signaling layer plane, an exterior layer plane, and a ground layer plane. A pair of differential signal lines implemented as strip-lines are within the signaling layer, and propagate electromagnetic interference (EMI) along the signaling layer. A dual slot common mode noise filter may be etched within the ground layer and may include a first U-shaped etching pair comprising a first U-shaped etching and a second U-shaped etching opposing the first U-shaped etching within the ground layer plane.
