Abstract

This paper demonstrates the deleterious effect of Near End Cross Talk (NEXT) on 25.78 Gb/s communication links from proximity of aggressors to the victim's receiver end. Modeling studies and experimental results clearly indicate that at these higher data rates, even shorter lengths 2mm) of tight coupling could effectively close the eye, particularly when the coupling is near the victim's receiver end. Hence particular care must be taken in layout design of constrained areas like chip package to ensure this form of NEXT coupling happening near the victim receiver end is avoided.

25Gb/s总线接收器附近NEXT耦合的影响
本文演示了近端串扰(NEXT)对攻击者到受害者接收端的25.78 Gb/s通信链路的有害影响。建模研究和实验结果清楚地表明,在这些较高的数据速率下,即使是较短(2mm)的紧密耦合也可以有效地闭上眼睛,特别是当耦合靠近受害者的接收器端时。因此,在芯片封装等受限区域的布局设计中必须特别注意,以确保避免在受害接收器端附近发生这种形式的NEXT耦合。
