What are the AC voltage overshoot specifications for Stratix II devices for voltages beyond those listed in the device handbook?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The AC voltage overshoot specifications for Stratix® II devices are shown in Table 5-2 of the Stratix II Device Handbook DC & Switching Characteristics (PDF).  Voltages above 4.5V are shown below:

Vin       Duty Cycle

4.6        9.07
4.65      7.31
4.7        5.89
4.75      4.75
4.8        3.83
4.85      3.09
4.9        2.50
5          1.63

These same values apply to the non-transceiver I/O pins of Stratix II GX devices.

Note, Table 5-1 shows the absolute maximum DC input voltage is 4.6V.  This is incorrect, the absolute maximum DC voltage is 4.0V which corresponds to the 100% duty cycle condition for overshoot voltages as shown in Table 5-2.
