Abstract :
A single-chip 4.25 Gb/s 32:1, 1:32 transceiver, meeting the emerging ANSI fiber channel (FC) standard, uses 0.25 /spl mu/m CMOS technology. To achieve 4.25 Gb/s operation, the features include: 1) an asynchronous tree-type 1:8 demultiplexer (DEMUX), 2) an 8 b to 10 b parallel-to-parallel frequency converter, and 3) comma-detection and word-alignment logic. The transceiver consumes 600 mW in 4.25 Gb/s operation with a 2.5 V supply. Higher-speed operation that that of a previous CMOS FC design is achieved.
