Notes to
Figure 2–2
:
(1) This is a top view of the silicon die. For exact pin locations, refer to the pin list and the Quartus II software.
(2) True differential (PPDS, LVDS, mini-LVDS, and RSDS I/O standards) outputs are supported in row I/O banks 5 and 6 only. External resistors are
needed for the differential outputs in column I/O banks.
(3) The LVPECL I/O standard is only supported on clock input pins. This I/O standard is not supported on output pins.
(4) The HSTL-12 Class II is supported in column I/O banks 4, 7, and 8.
(5) The differential SSTL-18 and SSTL-2, differential HSTL-18, and HSTL-15 I/O standards are supported only on clock input pins and phase-locked
loops (PLLs) 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.
(6) The differential HSTL-12 I/O standard is only supported on clock input pins and PLL output clock pins. Differential HSTL-12 Class II is supported
only in column I/O banks 4, 7, and 8.
(7) BLVDS output uses two single-ended outputs with the second output programmed as inverted. BLVDS input uses the LVDS input buffer.
(8) The PCI-X I/O standard does not meet the IV curve requirement at the linear region.
(9) The OCT block is located in the shaded banks 4, 5, and 7.
(10) The dedicated clock input I/O banks 3A, 3B, 8A, and 8B can be used either for HSSI input reference clock pins or clock input pins.
(11) Single-ended clock input support is available for dedicated clock input I/O banks 3B and 8B.
