6963 - CertusPro-Nx: What are the recommended LPDDR4 trace impedance for CertusPro-NX devices?

Solution: 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.
