Notes to Figure 5–1:
(1) Figure 5–1 is a top view of the Stratix silicon die, which corresponds to a top-down view of non-flip-chip packages
and a bottom-up view of flip-chip packages.
(2) Figure 5–1 is a graphic representation only. See the pin list and the Quartus II software for exact locations.
(3) Banks 9 through 12 are enhanced PLL external clock output banks.
(4) 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 1.0, and AGP 1× /2× .
(5) See “Differential Pad Placement Guidelines” on page 4–30. You can only place single-ended output/bidirectional
pads five or more pads away from a differential pad. Use the Show Pads view in the Quartus II Floorplan Editor to
locate these pads. The Quartus II software gives an error message for illegal output or bidirectional pin placement
next to a high-speed differential I/O pin.
Stratix Differential I/O Standards
Stratix devices provide a multi-protocol interface that allows
communication between a variety of I/O standards, including LVDS,
HyperTransport technology, LVPECL, PCML, HSTL Class I and II, and
LVDS, LVPECL, 3.3-V PCML,
and HyperTransport I/O Block
and Regular I/O Pins (4)
