JEDEC JESD22-A114” and changed “+/-5kV” to

“Class 3A”

Section 5.3, "Power

Consumption," on page 67

Corrected typo in the current consumption table

row title: “100BASE-TX /W TRAFFIC”

Section 5.3, "Power

Consumption," on page 67

Corrected typo in note regarding Ethernet

component current:

“The Ethernet component current is typically 41mA

in 100BASE-TX mode and 100mA in 10BASE-T

mode, independent of the 2.5V or 3.3V supply rail

of the transformer.”
