Abstract :
An IC designed for a high-speed broadband ISDN (integrated services digital network) switching system is described. The IC was fabricated using a Bi-CMOS RAM and logic gate array. The IC has functions for cell buffering, switching, and VCI conversion. It features a pipeline configuration and a high-speed ECL (emitter coupled logic) interface for a throughput of 1.2 Gbit/s. Tests confirmed accurate switching and high-speed operation up to 110 MHz, which corresponds to 1.8 Gbit/s throughput. An ATM (asynchronous transfer mode) switching system handling 512 150 Mbit/s channels can be constructed using this IC, and housed in four cabinets
