Stratix II Architecture

For more information on I/O standards supported by Stratix II I/O

banks, refer to the Selectable I/O Standards in Stratix II & Stratix II GX

Devices chapter in volume 2 of the Stratix II Device Handbook or the

Stratix II GX Device Handbook.

Stratix II devices contain eight I/O banks and four enhanced PLL external

clock output banks, as shown in Figure 2–57. The four I/O banks on the

right and left of the device contain circuitry to support high-speed

differential I/O for LVDS and HyperTransport inputs and outputs. These

banks support all Stratix II I/O standards except PCI or PCI-X I/O pins,

and SSTL-18 Class II and HSTL outputs. The top and bottom I/O banks

support all single-ended I/O standards. Additionally, enhanced PLL

external clock output banks allow clock output capabilities such as

differential support for SSTL and HSTL.

Notes to Table 2–16:

(1)

This I/O standard is only available on input and output column clock pins.

(2)

This I/O standard is only available on input clock pins and DQS pins in I/O banks 3, 4, 7, and 8, and output clock

pins in I/O banks 9,10, 11, and 12.

(3)

VCCIO is 3.3 V when using this I/O standard in input and output column clock pins (in I/O banks 9, 10, 11, and 12).

The clock input pins supporting LVDS on banks 3, 4, 7, and 8 use VCCINT for LVDS input operations and have no

dependency on the VCCIO level of the bank.

(4)

1.2-V HSTL is only supported in I/O banks 4,7, and 8.
