Notes to
(1) This is a top view of the silicon die. This is only a graphical representation. 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 1, 2, 5, and 6 only. External resistors
(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 3, 4, 7, and 8 only.
(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
(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
(7) BLVDS output uses two single-ended outputs with the second output programmed as inverted. BLVDS input uses the LVDS input buffer.

High-Speed Differential Interfaces in Cyclone III Devices
I/O pins on the Cyclone III device family are grouped together into I/O banks, and
each bank has a separate power bus. Cyclone III and Cyclone III LS devices have eight

Class II, which is only supported in column I/O banks. All differential I/O standards
are supported in all banks. The only exception is HSTL-12 Class II, which is only
supported in column I/O banks.
