Kintex-7 FPGAs Data Sheet: DC and AC Switching Characteristics
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 recommended
operating conditions at the V OL and V OH test points. Only selected standards are tested. These are chosen to ensure that
all standards meet their specifications. The selected standards are tested at a minimum V CCO with the respective V OL and
V OH voltage levels shown. Other standards are sample tested.
