Note 5: GTLP V_REF and V_TT are specified to 2% tolerance since signal integrity and noise margin can be significantly degraded if these supplies are noisy.
In addition, V_TT and R_TERM can be adjusted to accommodate backplane impedances other than 50Ω, within the boundaries of not exceeding the DC Abso-
lute I_OL ratings. Similarly V_REF can be adjusted to compensate for changes in V_TT.
