Notes:
1. This V_CCO range spans the lowest and highest operating voltages for all supported I/O standards. Table 11 lists the recommended V_CCO
range specific to each of the single-ended I/O standards, and Table 13 lists that specific to the differential standards.
2. See XAPP459, "Eliminating I/O Coupling Effects when Interfacing Large-Swing Single-Ended Signals to User I/O Pins."
3. Measured between 10% and 90% V_CCO.
