Notes to Figure 2–28:
(1) This is a top view of the silicon die.
(2) This is a graphic representation only. Refer to the pin list and the Quartus II software for exact pin locations.
(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 differential SSTL-18 and SSTL-2 I/O standards are only supported on clock input pins and PLL output clock
pins.
(5) The differential 1.8-V and 1.5-V HSTL I/O standards are only supported on clock input pins and PLL output clock
pins.
