Abstract

This paper presents a transmitter and receiver for high speed serial data links including pre-distortion and equalization circuits. The circuits allow data transmission over lossy copper channels up to 10 Gb/s and beyond. The transmitter uses a three tap FIR-filter for pre-distortion. A full rate FIR design allows a low latency and provides a smooth filter characteristic. An analog equalizer in the receiver with high-pass filter characteristic is implemented. Transmitter and receiver use high speed differential current mode logic without using passive inductors. Measurements over legacy channels show error free transmission (BER < 10^-12) of 11 Gb/s for a 5 meter long RG58 cable and 9 Gb/s over a state of the art 22 cm long dual inline memory module (DIMM)- motherboard channel
