This paper reports a high-speed time division switching system using GaAs ICs. It also describes high-speed switching technologies including the fabrication of a 4-channel time division switch, a multi/ demultiplexer and peripheral circuit ICs, each having more than a 2 Gb/s throughput capability. In addition, such key factors as synchronous LSI operation, optimum circuit board designing and LSI packaging are presented. Finally it reports a great success in High Definition TV (HDTV) time division switching operation.
