InP DHBT-based 1:2 DEMUX IC operating at up to 120 Gbit/s

A 1:2 demultiplexer (DEMUX) circuit has been successfully designed and manufactured using high-speed InP/InGaAs DHBT technology. The 1:2 DEMUX features proper operation at data rates up to 120 Gbit/s. At this data rate, a minimum eye opening of 150 mVpp is required at the data input of the IC for generating 60 Gbit/s output data with impeccable eye opening and a voltage swing of 530 mVpp
