Abstract :
This paper reports on the 50-Gbit/s 4:1 multiplexer (MUX) and 1:4 demultiplexer (DMUX) chip-set using InP HEMTs. In order to achieve high and wide-range bit-rate operation, timing design inside the ICs was precisely executed. The packaged MUX and DMUX achieved 50 Gbit/s back-to-back error-free operation for 2/sup 31/-1 pseudo-random bit streams (PRBS). Furthermore, the MUX operated from 4 to 50 Gbit/s with >1 V/sub pp/ output amplitude, and the DMUX exhibited >180-degrees phase margin from 4 to 50 Gbit/s for 2/sup 31/-1 PRBS.
