Differential pair geometry for integrated circuit chip packages

摘要

An integrated circuit chip package (1) is provided which incorporates one or more differential pairs (20) of signal lines coupled to an integrated circuit chip. The differential pairs each include a first signal line (21) and a second signal line (22). The first signal lines are non-coplanar with the second signal lines. The first signal lines of the differential pairs may be provided in a first plane. The second signal lines of the differential pairs may be provided in a second plane different from the first plane. A first ground plane (51) is provided adjacent the first signal lines and a second ground plane (52) is provided adjacent the second signal lines. The spacing of respective signal lines provides, among other things, the capability of having a greater density of differential pairs of signal lines within the planar area of an integrated circuit chip package.
