A 2,125-Gb/s transmitter meeting the specifications of the emerging ANSI Fi
ber Channel standard has been developed using BICMOS technology, This trans
mitter features 1) a fully bipolar 10:1 multiplexer (MUX) and a 2.125-GHz r
etimer for high-accuracy transmission of data, 2) an emitter-coupled logic
(ECL)-CMOS analog phase-locked loop, 3) pure ECL-level output for direct co
nnection to the currently available optical modules, and 4) BiCMOS process
technology that includes 0.25-mu m CMOS devices and 20-GHz bipolar devices,
The LSI serializes 32-bit-wide, 53.125-Mb/s data into 2.125-Gb/s data thro
ugh a CMOS 8B10B encoder. The chip area is 3 x 2 mm(2), and the power dissi
pation is 860 mW.
