Maximum Allowed Overshoot and Undershoot Voltage

During transitions, input signals may overshoot to the voltage listed in the following table and undershoot to –2.0 V for input currents less than 100 mA and periods shorter than 20 ns.

The maximum allowed overshoot duration is specified as a percentage of high time over the lifetime of the device. A DC signal is equivalent to 100% duty cycle.

For example, a signal that overshoots to 2.70 V for LVDS I/O can only be at 2.70 V for ~4% over the lifetime of the device.

Table 2.  Maximum Allowed Overshoot During Transitions for Intel® Arria® 10 DevicesThis table lists the maximum allowed input overshoot voltage and the duration of the overshoot voltage as a percentage of device lifetime. The LVDS I/O values are applicable to the VREFP_ADC and VREFN_ADC I/O pins.
Symbol Description Condition (V) Overshoot Duration as % at TJ = 100°C Unit
LVDS I/O 7 3 V I/O
Vi (AC) AC input voltage 2.50 3.80 100 %
2.55 3.85 42 %
2.60 3.90 18 %
2.65 3.95 9 %
2.70 4.00 4 %
> 2.70 > 4.00 No overshoot allowed %

For an overshoot of 2.5 V, the percentage of high time for the overshoot can be as high as 100% over a 10-year period. Percentage of high time is calculated as ([delta T]/T) × 100. This 10-year period assumes that the device is always turned on with 100% I/O toggle rate and 50% duty cycle signal.
