摘要

在IEEE 802.3ba标准中，集成串扰噪声(ICN)被广泛用于替代插入串扰比(ICR)来评估信道串扰。本文首先在两个相邻的差分对上实现了基于正交性思想的差分ICN缓解方案。在SerDes通道的全引脚图区域，提出了基于该方案的新引脚图，并与传统的泛图图进行了比较。新的引脚图大大减轻了差分ICN，但保持了G:s比。初步研究了扇形出迹布线，以保持新的引脚图模式的优势。

Differential Integrated Crosstalk Noise (ICN) Mitigation in the Pin Field Area of SerDes Channel

The integrated crosstalk noise (ICN) has been widely used as an alternative to the insertion crosstalk ratio (ICR) for channel crosstalk evaluation in the IEEE 802.3ba standard. In this work, the differential ICN mitigation scheme by using idea of orthogonality is implemented in two adjacent differential pairs first. In the full pin map area of SerDes channel, new pin map patterns based on such scheme are prosed and compared with the conventional pan map patterns. The new pin maps mitigate the differential ICN drastically, yet maintain the G:s ratio. A preliminary study is conducted on fan-out trace routing to maintain the benefit from new pin map patterns.
