a. Input have internal pullup/pulldown resistors which affect the input current

b. VPP (DC) is the minimum differential input voltage swing required to maintain device functionality

c. VCMR (DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the VCMR (DC)

range and the input swing lies within the VPP (DC) specification.

d. Equivalent to a termination of 50

W to VTT.

e. ICC calculation: ICC = (number of differential output pairs used) x (IOH + IOL) + IEE

ICC = (number of differential output pairs used) x (VOH – VTT)/Rload + (VOL – VTT)/Rload + IEE.
