Notes:
1. Functional and tested operating conditions are given in
Table 3. Absolute maximum ratings are stress ratings only, and
functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause
permanent damage to the device.
2. Caution: MVIN must not exceed GVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during
power-on reset and power-down sequences.
3. Caution: OVIN must not exceed OVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during
power-on reset and power-down sequences.
4. (M,O)VIN and MVREF may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2. 5. Overshoot/undershoot by OVIN on the PCI interface does not comply to the PCI Electrical Specification for 3.3-V operation,
6. L[1,2]_
nVDD includes SDAVDD_0, XCOREVDD, and XPADVDD power inputs.
