HFTA-13.0: Designing External Cabling for Low EMI Radiation


Abstract: The use of integrated circuits for equalization of cable loss has enabled a major reduction in the cost of interconnects for communication systems. For optimum performance such systems must minimize radiated emissions from the cables and connectors. Cables and connectors that interconnect various pieces of equipment should be specified to prevent interference, and to prevent the reciprocal effect of susceptibility to radiated energy. This article, which includes cable equalization to extend transmission distance and lower system costs, presents simple methods for reducing radiation to low levels.
