Notes to Table 4–2:
(1) This bank is not available in Stratix II GX Devices.
(2) A mixture of single-ended and differential I/O standards is not allowed in enhanced PLL external clock output
bank.
(3) This I/O standard is only supported for the input operation in this I/O bank.
(4) Although the Quartus II software does not support pseudo-differential SSTL/HSTL I/O standards on the left and
right I/O banks, you can implement these standards at these banks. Refer to the “Differential I/O Standards” on
page 4–10 for details.
(5) This I/O standard is supported for both input and output operations for pins that support the DQS function. Refer
to the “Differential I/O Standards” on page 4–10 for details.
(6) This I/O standard is only supported for the input operation for pins that support PLL INCLKfunction in this I/O
bank.
