PCIe Gen4 enables new wave of innovation to guide inner-loop SerDes optimization assisted by outer-loop system optimization. This paper introduces an outer-layer equalization scheme for managing SerDes inner-layer equalization to optimize overall system-level aggregate performance.

In the GB/s regime, accurate modeling of insertion loss and phase delay is a precursor to successful high-speed serial link designs. We propose a causal (physically meaningful) form of the Hammerstad and Cannonball-Huray metal roughness frequency dependent complex correction factor. Compared to the widely used, non-causal form, it considerably increases the inductive component of internal metal impedance. Transmission lines simulated with a causal version demonstrate increased phase delay and characteristic impedance. By obtaining the dielectric and roughness parameters solely from manufacturers' data sheets, we validate the model through a detailed case study to test its accuracy.
