A 0.18μm SiGe BiCMOS receiver and transmitter chipset for SONET OC-768 transmission systems

Abstract

A BiCMOS CDR/1:4-DEMUX and CMU/4:1-MUX chipset targeting 40-43Gb/s optical communications is implemented in 0.18μm SiGe. At 43Gb/s and up to 100°C chip temperature, both ICs operate at BER <10-15 and <210fs RMS clock jitter. The receiver and transmitter chips dissipate 2.8W and 2.3W, respectively, from a -3.6V supply.
