摘要

本文对目前提出的1000BASE-T1共模终端(CMT)进行了分析。特别是计算了该电路的复杂混合模式散射参数随频率的变化。此外,还使用简单的印刷电路板进行了模拟和测量。总而言之,所得结果显示出很好的一致性。在此基础上,最后对CMT进行了评价。可以说,当前的电路设计仅在非常有限的程度上减小了共模。

Analysis and Assessment of the Common Mode Termination for Automotive Ethernet 1000BASE-T1
In this work the currently proposed common mode termination (CMT) for 1000BASE-T1 is analyzed analytically. Especially the complex mixed mode scattering parameters of this circuit are calculated as a function of frequency. In addition, simulations and measurements are performed using a simple printed circuit board. All in all, the obtained results show a very good agreement. Based on this, an evaluation of the CMT is finally performed. It can be stated that the current circuit design reduces the common mode only to a very limited extent.
