Abstract
A apparatus is described herein for configuring Input/Output (I/O) conductors on an integrated circuit (IC) or in a socket. At least a portion of the I/O conductors for an IC and/or contacts/receptacles of a socket are configured in a repeatable 2×4 rectangular T pattern. The rectangular T pattern includes a first line of four conductors, which include two ground conductors and a first differential pair of conductors, and a second line of four conductors, which include a second and a third pair of differential conductors. The I/O conductors on the IC may be pads/lands in an land-grid-array (LGA) style socket, pins in a pin-grid-array (PGA) style socket, or other conductor in another style of socket, while the socket includes corresponding contacts, receptacles, etc.
