Abstract:
1. An electrical backplane comprising: a plurality of high-speed signaling layers; a plurality of primary power supply planes; at least one digital ground plane interposed between the primary power supply planes and the high-speed signaling layers; and a high-speed connector region on the backplane, the high-speed connector region comprising multiple conductive high-speed signaling throughholes and multiple conductive digital ground throughholes arranged on the backplane such that, on at least one of the primary power supply planes, the high-speed connector region comprises a first conductive plane section that is electrically isolated from a power supply section of the at least one of the power supply planes, the first conductive plane section electrically isolated from the high-speed signaling throughholes by clearances, the first conductive plane section electrically connected to at least one of the digital ground throughholes.
