A 0.35 /spl mu/m CMOS 4.8 Gb/s 4:1 multiplexer

A 4.8 Gbit/s 4:1 multiplexer was designed in source coupled logic and fabricated in 0.35 /spl mu/m CMOS technology. It has a power dissipation of less than 1W from a 5V supply and a size of 1/spl times/1.05 mm/sup 2/, and can be directly applied to an optical fiber link at STM-16 (2.488 Gbit/s) level of synchronous digital hierarchy (SDH).
