1) Under all conditions, VDDQ must be less than or equal to VDD
2) Peak to peak AC noise on VREF may not exceed ± 2% VREF (DC).VREF is also expected to track noise variations in VDDQ.
3) Input voltage for any connector pin under test of 0 V ≤ VIN ≤ VDDQ + 0.3 V; all other pins at 0 V. Current is per pin
