Abstract

Fabricated in 90nm CMOS, the chip consumes 545mW and has a pattern-balancing adaptive equalizer that is stable for any data patterns including those with a strong peak component at a single frequency. The adaptive equalizer yields a gain at f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</sub> /2 relative to f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</sub> /16 varying from -1.7 to 2.2dB for any 8B10B encoded Ethernet frames filled with a fixed data byte
