摘要

随着互连密度和封装密度的不断提高，串扰在输入/输出(I/O)设计中变得越来越重要。多模信号已被研究用于串扰消除。提出了一种基于散射参数(s参数)的多模信号分析方法。从整个信道的s参数得到编解码器系数集(CODEC)，使该方案更适用于实际系统。在实际的基准测试问题中，与单端信令相比，该编码解码器的信噪比提高了20 dB，均方根抖动降低了45%。

S-parameter based multimode signaling

As the demands for higher density of interconnects and denser packages are increasing, crosstalk is becoming more important in input/output (I/O) design. Multimode signaling has been investigated for crosstalk cancellation. This paper presents a new scattering parameter (S-parameter) based methodology for multimode signaling. The set of coder/decoder coefficients (CODEC) is obtained from the S-parameters of the whole channel, which makes the scheme more applicable for practical systems. The derived CODEC shows a 20 dB improvement in signal-to-noise ratio and 45% reduction of root mean square (RMS) jitter compared with single-ended signaling for a practical benchmark problem.
