ICM2 IC: A new ATM switching element for 2.48 Gb/s communications

The ICM2 circuit is part of a new ATM (Asynchronous Transfer Mode) switch core of a new Broad Band ISDN exchange system that can switch at least 2.488 Gb/s. It is being developed by TELEFONICA I+D for the Spanish PTT, TELEFONICA. The circuit was processed with a 0.7 micron CMOS technology, and a first silicon success has been obtained. Its die size is 12.8/spl times/12.1 sqmm and its working frequency is 70 MHz.<
