A Bi-CMOS ATM switching LSIC

An IC designed for a high-speed broadband ISDN switching system is described. The IC was fabricated using a BiCMOS 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. Using this IC, an ATM (asynchronous transfer mode) switching system handling 512 150 Mbit/s channels can be constructed and housed in four cabinets.<
