Ω (±10%)
100Ω is the spec. target. 95/85Ω are
implementation options (Zdiff does not
account for trace coupling)
95Ω should be used to support DP-HDMI
co-layout as HDMI 2.0 requires 100Ω
impedance (see HDMI section for addition of
series resistor RS).
85Ω can be used if eDP/DP only and is
preferable as it provides better trace loss
characteristic performance. See Note 1.
