SILICON BIPOLAR CHIPSET FOR SONET SDH 10-GB/S FIBEROPTIC COMMUNICATION LINKS/

High-speed multiplexers, demultiplexers, frequency dividers, mixers, a nd amplifiers are key electronic components in high-speed fiber-optic communications systems such as SONET/SDH. In this paper, we present se veral important digital and analog integrated circuits (IC) which have been developed for use in SONET/SDH 10 Gb/s optical communication lin ks, The circuits have been fabricated in MOSAIC 5E, an advanced silico n bipolar technology (f(T) = 26 GHz), The resulting chipset which amou nts to a total of 10 IC's consists of multiplexers, demultiplexers, a regenerative frequency divider (2:1), a dual output limiting amplifier , and two different types of mixers for clock extraction, Specifically , the design and performance of these IC's and a hybrid clock recovery module are discussed, The high performance and potential tow cost of this research chipset show that advanced silicon bipolar circuit techn ology can play an important role in future multigigabit fiber-optic co mmunication systems.
