Differential far-end crosstalk cancellation — Implementations and challenges

This paper is a follow-up of the paper published in 2011 IEEE EMC symposium, where a new type of far-end crosstalk cancellation for differential signal was proposed. Since then, various implementation schemes had been attempted in system designs. However, it turned out that due to routing constraints, the implementation on a production board can be very challenging. The authors will discuss what the challenges are and how we mitigate it. Furthermore, lab results will also be presented to demonstrate the effectiveness of crosstalk cancellation in products.
