Notes to
(1) The PCI-X I/O standard does not meet the IV curve requirement at the linear region.
(2) The RSDS, mini-LVDS, and PPDS I/O standards are only supported on output pins. These I/O standards are not supported on input pins.
(3) The LVPECL I/O standard is only supported on dedicated clock input pins. This I/O standard is not supported on output pins.
(4) The differential SSTL-2, SSTL-18, HSTL-18, HSTL-15, and HSTL-12 I/O standards are only supported on dedicated clock input pins and PLL
(5) BLVDS output uses two single-ended outputs with the second output programmed as inverted. BLVDS input uses LVDS input buffer.

output clock pins. PLL output clock pins do not support Class II interface type of differential SSTL-18, HSTL-18, HSTL-15, and HSTL-12 I/O
standards.
