Achieving EMI compliance with DVI and HDMI on defense/aerospace platforms

Digital visual interface (DVI) and high definition multimedia interface (HDMI) have become very popular digital interfaces in the consumer electronics arena for high definition video and audio with personal computers and in-home theatre systems. Due to the off-the-shelf availability of hardware and software that supports these interfaces, DVI and HDMI present the opportunity to provide the aircraft industry and the war fighter with state-of-the-art high-definition video capabilities today. However, these interfaces were not designed for the defense/aerospace electromagnetic effects environments. This paper presents guidelines with respect to circuit modification and cable/connector system design to allow compliance with defense/aerospace equipment EMI standards such as MIL-STD-461E and DO-160E.
