LAN8810/LAN8810I

Note 5-8

When the external magnetics operate at +2.5V, current consumption remains the same. However,

Ethernet component power consumption will be reduced accordingly.

Note 5-9

When the external magnetics operate at +2.5V, current consumption remains the same. However,

Ethernet component power consumption will be reduced accordingly.

Note 5-10

When the external magnetics operate at +2.5V, current consumption remains the same. However,

Ethernet component power consumption will be reduced accordingly.
