43 Gb/s full-rate-clock 16:1 multiplexer and 1:16 demultiplexer with SFI-5 interface in SiGe BiCMOS technology

Fabricated in 0.18 /spl mu/m SiGe BiCMOS, 16:1 MUX and 1:16 DMUX MCMs equipped with an SFI-5 interface operate at 43 Gb/s. The on-chip CDR with external VCO recovers a full-rate clock with 2.5/spl deg/ RMS jitter from 2/sup 31/-1 PRBS. The SFI-5 bus also operates error-free at 2.7 Gb/s, and tolerates a /spl plusmn/6.6 Ul static skew.
