Abstract

The VLSI integrated circuit “Elemento de Cruce” (EC) has been conceived as a multifunction device. The EC has been designed to work as the crosspoint element in a broadband (ATM) asynchronous transfer mode (ATM) switch block, as well as an interfacing device between a microprocessor, a codec or, in general, any data source and the ATM switch network. The EC works at a frequency of 43.75 MHz using a 16 bit parallel data format, giving a throughput of 700 Mbs. The chip is implemented with 13 K CMOS gates, 4 kbits of RAM memory and 25.5 kbits of FIFO memory. The IC is manufactured in 1.25 μm twin-tub double metal level standard cell CMOS technology and has dimensions of 400 mils×400 mils, with nominal power dissipation of 1.3 W
