a. The power consumption for 1000 Mbps is not shown since the controller moves to the 10/100 Mbps mode before
going into the D3 state 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.
