Signal Integrity of a Multimedia Link

摘要

In one embodiment, a source device and sink device communicate with one another via a multimedia link. The multimedia link includes a cable and a plug. The cable includes one or more data lines, power lines, ground lines or control bus lines. The plug includes a plurality of pins each connected to the one or more lines included in the cable. The plug also includes a ground plane and a power plane, wherein a ground pin of the plug connects the ground plane to the ground line of the cable of the multimedia link and a power pin of the plug connects the ground plane to the power line of the cable. In one example, the ground plane and power plane are placed within a threshold distance of one another, such that the power line connected to the power plane via the power pin behaves as a signal return path.
