Notes to Figure 1–1:
(1) Figure 1–1 is a top view of the Stratix GX silicon die.
(2) Banks 9 through 12 are enhanced PLL external clock output banks.
(3) If the high-speed differential I/O pins are not used for high-speed differential signaling, they can support all of the
I/O standards except HSTL class I and II, GTL, SSTL-18 Class II, PCI, PCI-X, and AGP 1×/2×.
(4) For guidelines for placing single-ended I/O pads next to differential I/O pads, see the Selectable I/O Standards in
Stratix & Stratix GX Devices chapter of the Stratix GX Device Handbook, Volume 2.
(5) These I/O banks in Stratix GX devices also support the LVDS, LVPECL, and 3.3-V PCML I/O standards on
reference clocks and receiver input pins (AC coupled).
Stratix GX devices contain a two-dimensional row- and column-based
architecture to implement custom logic. A series of column and row
interconnects of varying length and speed provide signal interconnects
between logic array blocks (LABs), memory block structures, and DSP
blocks.
