Intra-Pair Skew Propagation Graph (ISPG): An Analytical Model for Cascaded Channels

Amendra Koul, David Nozadze, Mike Sapozhnikov, Sayed Ashraf Mamun, Srinath Penugonda, Zurab Kiguradze

A graph-based model called ISPG calculates cumulative intra-pair skew in cascaded high-speed channels by integrating it with S-parameter calculations.

Claims

C1strongest claim

We introduce the Intra-pair Skew Propagation Graph (ISPG), a novel graph-based methodology for calculating cumulative skew in complex, cascaded channels. The proposed framework is validated against both S-parameter simulations and empirical measurements of a 2m twinax cable assembly, demonstrating excellent accuracy and robustness for high-speed interconnect design.

C2weakest assumption

That intra-pair skew in generic asymmetric coupled transmission lines can be explicitly and accurately integrated into S-parameter formulations such that the graph-based propagation model captures cumulative effects without significant unmodeled interactions or losses.

C3one line summary

Presents the Intra-pair Skew Propagation Graph (ISPG) as a novel analytical framework for modeling cumulative intra-pair skew in complex cascaded channels by integrating skew into S-parameter formulations.
