Summary: 
This paper describes ALINX (Advanced Low-voltage Interface Circuit System), a low-power and high-speed interface circuit of submicron CMOS LSI for digital information and telecommunications systems. Differential and single-ended ALINXs are low-voltage swing I/O interface circuits with less than 1.0 V swing from a 1.2 V supply. Specifically, the differential ALINX features a pair of complementary NMOS push-pull drivers operating from a 1.2 V supply, reducing power consumption compared to conventional high-speed interface circuits operating from a 5 V or 3.3 V supply. The DC power consumption is approximately 11% of ECL. We observed 622 Mbps differential transmission with 8 mW power consumption and single-ended transmission at 311 Mbps with 14 mW with a PN23 pseudo-random pattern. We also describe a noise characteristic and ALINX applications to high-speed data buses and LSI for telecommunications systems. A time/space switch LSI with 0.9 W total power consumption was fabricated by 0.5 µm CMOS process technology. This chip can use a plastic QFP.
