Note 4: All typical values are at VCC = 5.0V and TA = 25°C.
Note 5: GTLP VREF and VTT are specified to 2% tolerance since signal integrity and noise margin can be significantly degraded if these supplies are noisy.
In addition, VTT and RTERM can be adjusted to accommodate backplane impedances other than 50Ω, within the boundaries of not exceeding the DC Abso-
lute IOL ratings. Similarly VREF can be adjusted to compensate for changes in VTT.
