A 5-Gb/s/pin Transceiver for DDR Memory Interface With a Crosstalk Suppression Scheme

Abstract

A 5-Gb/s/pin transceiver for DDR memory interface is proposed with a crosstalk suppression scheme. The proposed transceiver implements a staggered memory bus topology and a glitch canceller to suppress crosstalk-induced distortions in a memory channel. The transceiver is implemented using 0.18 mum CMOS process and operates at 5 Gb/s. The results demonstrate widened eye diagram and lower bit error rate. The eye width and height of the proposed scheme increases 28.3% and 11.1% compared to the conventional memory transceiver, respectively. The peak-to-peak jitter of output data is 52.82 ps.
