A CMOS 2.4 Gbps 16×16 ATM switch chip set

The authors have developed a CMOS chip set for a 2.4 Gbps 16 × 16 ATM switch. In order to realize higher link speed and more maximum switch throughput that past development ATOM (ATM Output buffer Modular switch), a parallel-bit synchronization scheme without external timing adjustment, ECL-compatible I/O buffers and a newly LSI package that has thin film termination resistors have been developed. This chip set consists of three LSI chips with 0.55 μm CMOS technology. From the result of evaluation of these LSI chips, the authors have achieved a link speed of 2.4 Gbps
