Asynchronous transfer mode switching LSI chips with 10-Gb/s serial I/O ports

LSI chips were developed that fit on a switching fabric using chip-to-chip optical interconnections; they have 10-Gb/s serial input and output ports, which facilitates the layout of optically interfaced switching element modules. A test switching module composed of these chips was operated at 10.2 Gb/s without bit errors. Ultrahigh-speed switching LSI chips have been developed for a future asynchronous transfer mode (ATM) switching system with an over-Tb/s capacity. Their serial input and output ports facilitate chip-to-chip optical interconnection. Cell-dropper and crosspoint-router LSI chips, composing the core of the switching element, were fabricated by using GaAs LSI technology. A test switching module composed of these chips was operated at 10.2 Gb/s without bit errors. >
