Abstract

The use of current methods of length matching in differential microstrip transmission lines when used with data-rates up to 15 GHz is explored. It is shown that using current methods of length matching could make worse mode conversion and EM loss than with no length matching at all. A new method is suggested whereby interconnect geometry can be engineered to match the length of a pair at a specific or dominant frequency, while also minimizing reflections. This is achieved through appropriate engineering of de-skew wiglets, variation of their positioning, geometry and number.

高达15GHz的差分微带线的歪斜和EMI管理

探讨了当前差分微带传输线长度匹配方法在数据速率高达15ghz时的应用。结果表明，与不进行长度匹配相比，采用现有的长度匹配方法会造成更大的模式转换和电磁损耗。提出了一种新的方法，即可以设计互连几何形状以匹配特定或主导频率下的一对的长度，同时也最小化反射。这是通过适当的工程去斜小波，他们的位置，几何形状和数量的变化来实现的。
