For more information about the I/O standards supported by Arria GX I/O banks,
refer to the
Arria GX devices contain six I/O banks and four enhanced PLL external clock output
banks, as shown in
circuitry to support source-synchronous, high-speed differential I/O for LVDS inputs
and outputs. These banks support all Arria 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.
