At high data rates, components or elements within the signal path must be treated as RF elements. Parasitic due to these elements can introduce impedance mismatch, return loss degradation, common mode noise, cross talk, plus other interference sources. Additionally, temperature and humidity side effects must be considered. Using 3D HFSS PCB simulations and close examination of previous design can facilitate and provide a more deterministic approach to a high-speed PCB design.
