1. Maximum conditions refer to fast silicon, high temperature and nominal VCC.
2. For 10/100 Mb/s non-stress mode with Intel® AMT, add 12 mW to this number (for example,
using IDE-R functionality).
3. For 10/100 Mb/s stress mode active Intel® AMT, add 120 mW to this number (for example, using
IDE-R functionality).
4. The current use is slightly higher in the device off state than in the no link state. This occurs since
a PHY reset is required in the device off state, which overrides the PHY power down.
