Operating Conditions
Notes:
1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions is not
guaranteed.
2. PCI pins are designed to withstand LVdd + 0.5V DC when LVdd is connected to a 5.0V DC power supply.
3. PCI pins are designed to withstand LVdd + 0.5V DC when LVdd is connected to a 3.3V DC power supply.
4. Caution: Input voltage (V
IN
) must not be greater than the supply voltage (Vdd/AVdd/AVdd2/LAVdd) by more than 2.5V at all
times including during power-on reset.
5. Caution: OVdd must not exceed Vdd/AVdd/AVdd2/LAVdd by more than 1.8V at any time including during power-on reset.
6. Caution: Vdd/AVdd/AVdd2/LAVdd must not exceed OVdd by more than 0.6V at any time including during power-on reset.
7. Caution: GVdd must not exceed Vdd/AVdd/AVdd2/LAVdd by more than 1.8V at any time including during power-on reset.
8. Caution: LVdd must not exceed Vdd/AVdd/AVdd2/LAVdd by more than 5.4V at any time including during power-on reset.
9. Caution: LVdd must not exceed OVdd by more than 3.6V at any time including during power-on reset.
