Abstract :
A gallium arsenide 8:1 multiplexer (MUX) and a 1:8 demultiplexer (DEMUX) for 2.4 Gbps optical communication systems have been developed. These LSIs employ a tree-type architecture using 2:1 MUXs/1:2 DEMUXs that is suitable for high-speed and low power operation but requires precise control of clock timing. To ensure timing margins, a new timing generator and clock buffer circuit have been developed. These LSIs operate at over 2.4 Gbps with 150-mW of power consumption at a supply voltage of 0.7 V.
