Table 1. VIN Maximum Allowed AC Voltage Overshoot and Undershoot for HDIO and PSIO Banks
AC Voltage Overshoot 1 % of UI 2 at –40°C to 100°C AC Voltage Undershoot 1 % of UI 2 at –40°C to 100°C
VCCO + 0.20 100% –0.20 100%
VCCO + 0.25 100% –0.25 75%
VCCO + 0.30 75% –0.30 75%
VCCO + 0.35 75% –0.35 75%
VCCO + 0.40 75% –0.40 60%
VCCO + 0.45 50% –0.45 30%
VCCO + 0.50 30% –0.50 0%
VCCO + 0.55 20% –0.55 0%
VCCO + 0.60 20% –0.60 0%
VCCO + 0.65 10% –0.65 0%
VCCO + 0.70 10% –0.70 0%
VCCO + 0.75 10% –0.75 0%
VCCO + 0.80 10% –0.80 0%
VCCO + 0.85 8% –0.85 0%
VCCO + 0.90 6% –0.90 0%
VCCO + 0.95 2% –0.95 0%
  1. A total of 200 mA per bank should not be exceeded.
  2. For UI smaller than 20 µs.
Table 2. VIN Maximum Allowed AC Voltage Overshoot and Undershoot for XPIO Banks
AC Voltage Overshoot 1 % of UI 2 at –40°C to 100°C AC Voltage Undershoot 1 % of UI 2 at –40°C to 100°C
VCCO + 0.20 100% –0.20 100%
VCCO + 0.25 100% –0.25 100%
VCCO + 0.30 100% –0.30 10%
VCCO + 0.35 100% –0.35 0%
VCCO + 0.40 96% –0.40 0%
VCCO + 0.45 2% –0.45 0%
  1. A total of 200 mA per bank should not be exceeded.
  2. For UI smaller than 20 µs.
  3. In XPIO banks, VIN overshoot above VCCO and undershoot below GND can reduce the performance of VREF-based receivers within the same nibble.
