A 2.125-Gb/s BiCMOS fiber channel transmitter for serial datacommunications

摘要

A 2.125-Gb/s transmitter meeting the specifications of thenemerging ANSI Fiber Channel standard has been developed using BiCMOSntechnology. This transmitter features (1) a fully bipolar 10:1nmultiplexer (MUX) and a 2.125-GHz retimer for high-accuracy transmissionnof data, (2) an emitter-coupled logic (ECL) CMOS analog phase-lockednloop, (3) pure ECL-level output for direct connection to the currentlynavailable optical modules, and (4) BiCMOS process technology thatnincludes 0.25-Μm CMOS devices and 20-GHz bipolar devices. The LSInserializes 32-bit-wide, 53.125-Mb/s data into 2.125-Gb/s data through anCMOS 8B10B encoder. The chip area is 3×2 mm2, and thenpower dissipation is 860 mW
