a. At 1000 Mbps, power consumption is not shown since the controller switches to the 10/100 Mbps state before entering D3 to
conserve power.
b. Typical conditions: operating temperature (T_A) = 25 C, nominal voltages, moderate network traffic at full duplex, and PCI 33
MHz system interface.
c. Maximum conditions: minimum operating temperature (T_A) values, maximum voltage values, continuous network traffic at full
duplex, and PCI 33 MHz system interface.
