For example, if LVTTL 3.3V (V
other available (i.e. compatible) I/O standards in the
same bank are LVTTL 3.3V PCI/PCI-X, GTL+, and LVPECL.

Notes:
1. Note that GTL+ 2.5V is not supported across the full military temperature range.
2. A "✓" indicates whether standards can be used within a bank at the same time.
Examples:
a) LVTTL can be used with 3.3V PCI and GTL+ (3.3V), when V
b) LVTTL can be used with 3.3V PCI and SSTL3 Class I and II, when V

Also note that when multiple I/O standards are used
within a bank, the voltage tolerance will be limited to
the minimum tolerance of all I/O standards used in the
bank.
