Interface that permits data bus signals to pass between high frequency processing unit and low frequency expansion devices |
摘要 |
An interface module for an electronic system that permits signals to pass between a high frequency main circuit board area such as used for central processing units, memories, or other relatively high clock rate components and a low frequency circuit area such as used for standard peripheral circuit modules used for disk drives, video interfaces and the like. The interconnect module is positioned near an opening in a sheet metal bulkhead used as an electromagnetic interference (EMI) barrier around the main circuit area. The interface module uses a connector that is surrounded by one or more conductive shields that contain metal fingers on inboard and outboard sides to provide a ground connection between the interface module and the EMI barrier.
