A 100-Gb/s 1:2 Demultiplexer

A 100-Gbit/s 1:2 demultiplexer (DEMUX) has been developed using InP HBT technology. The IC features broadband impedance matching with double terminations and transmission lines with a low phase constant in the data and clock distributions to obtain high signal quality and a large timing margin. Excellent eye diagrams with 550-mV
