Experimental gigabit multidrop serial backplane for high speed digital systems

Maximum data rate in today's available multidrop backplanes is limited to 400 Mbps due to signal integrity concerns. In this paper, an experimental gigabit multidrop serial backplane for high-speed digital systems based on a novel asymmetrical broadband power splitter configuration with matching trace impedance, is presented. Experimental results obtained from constructed prototype demonstrate a satisfactory operation of the proposed multidrop serial backplane for a data transfer rate of 3 Gbps.
