The numbers in this table are based on the conditions set forth in
Output voltage measurements for all differential standards are made with a termination resistor (R
differential signal pair. The exception is for BLVDS, shown in
At any given time, no more than two of the following differential output standards may be assigned to an I/O bank: LVDS_25, RSDS_25,
