CertusPro-Nx: What are the recommended LPDDR4 trace impedance for CertusPro-NX devices?SupportArticlePagef6dba12f-2f5d-4b2b-95e7-1560671c1209FAQ/Support/AnswerDatabase/6/9/6/6963https://edge.sitecorecloud.io/latticesemi9e32-latticesemi06bb-prod9ecc-d341/media/Project/Lattice/LatticeSemi/Images/SearchThumbnails/FAQ.png?sc_lang=enSolution: There are three options presented: - 50-ohm single-ended with 100-ohm differential - 40-ohm single-ended with 80-ohm differential - 48-ohm single-ended with 96-ohm differential Here are some notes from our SME regarding the trace impedance options: - 40/80 takes a bit more power than 48/96. - 40/80 tends to have a little better signal integrity than 48/96.
