Table 8–6. Hardcopy II Supported I/O Standards on User I/O Pins (Part 2 of 2)
Like Stratix II devices, the optional PCI clamp is only available on column I/O pins. General purpose IOEs on the
right row I/O pins do not support the PCI clamp.
Similar to Stratix II devices, these I/O standards are only available on input clock pins, output clock pins in I/O
banks 9, 10, 11, 12, and DQS pins in top I/O banks 3, 4 for all HardCopy II devices, and DQS pins in bottom I/O
banks 7 and 8 for HC230 and HC240 devices.
Pseudo-differential HSTL and SSTL inputs only use the positive polarity input in the speed path. The negative
input is not connected internally. Pseudo-differential HSTL and SSTL outputs use two single-ended outputs with
the second output programmed as inverted. This is similar to a Stratix II device implementation.
