a. Sustained operation of the device at conditions exceeding these values, even if they are within the absolute maximum rating
limits, might result in permanent damage.
b. It is recommended for VDDO to equal AVDDH (VDDO = AVDDH) during power-up and normal operation.
c. It is recommended for both VDDO and AVDDH to be of a value greater than AVDDL, with a value greater than DVDD, during
power-up (VDDO or AVDDH > AVDDL > DVDD). However, voltage sequencing is not a strict requirement if the power supply
ramp must be faster than approximately 200 ms.

a. Typical conditions: operating temperature (TA) = 25 C, nominal voltages, moderate network traffic at full duplex, and PCI 66 MHz
system interface.
b. Maximum conditions: minimum operating temperature (TA) values, maximum voltage values, continuous network traffic at full
duplex, and PCI-X 100 to 133 MHZ system interface.
