1-W 1:16 DEMUX and one-chip CDR with 1:4 DEMUX for 10 Gbit/s optical communication systems
Description
Using InP/InGaAs heterojunction bipolar transistor (HBT) technology, we have successfully designed and fabricated a low power 1:16 demultiplexer (DEMUX) IC and one-chip clock and data recovery (CDR) with a 1:4 DEMUX IC for 10 Gbit/s optical communication systems. The HBTs were fabricated by a non-self-aligned process to achieve high productivity and uniformity of device characteristics. The 1:16 DEMUX IC and the one-chip CDR with the 1:4 DEMUX IC consist of approximately 1200 and 460 transistors, respectively. We have confirmed error-free operation at 10 Gbit/s for all data outputs of both ICs. The 1:16 DEMUX IC and the one-chip CDR with the 1:4 DEMUX IC consume only 1 W and 950 mW, respectively. These results demonstrate the feasibility of InP/InGaAs HBTs for low-power, high-integration optical communication ICs.
