3-Gb/s, Single-ended Adaptive Equalization of Bidirectional Data over a Multi-drop Bus

Abstract

This paper presents a design for single-ended adaptive equalization. The design enables mitigation of inter-symbol interference in communication systems where it is desirable to utilize signal processing resources on only one side of a communication channel. Utilizing the reciprocity principle we show that this idea is suitable for both point-to-point and point-to-multi-point links. Simulation results show that the presented design can mitigate ISI generated by a four drop memory bus at 3 Gb/s.
