Virtex-II Pro and Virtex-II Pro X Platform FPGAs: DC and Switching Characteristics
SelectIO-Ultra DC Input and Output Levels
Values for V_IL and V_IH are recommended input voltages.
Values for I_OL and I_OH are guaranteed over the recom-
mended operating conditions at the V_OL and V_OH test
points. Only selected standards are tested. These are cho-
sen to ensure that all standards meet their specifications.
The selected standards are tested at minimum V_CCO with
the respective V_OL and V_OH voltage levels shown. Other
standards are sample tested.
