Devices
Stratix II GX devices contain six I/O banks and four enhanced PLL
external clock output banks, as shown in
on the left of the device contain circuitry to support source-synchronous,
high-speed differential I/O for LVDS inputs and outputs. These banks
support all Stratix II GX 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.
