A 0.18 /spl mu/m SiGe BiCMOS receiver and transmitter chipset for SONET OC-768 transmission systems

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