Transmit Current Set
A resistor connected between the REXT pin and GND
sets the output current for the TP transmit outputs.
Twisted-Pair Transmit Output (Positive)
The TPO+ pin functions as the positive signal in the
twisted-pair output.
Twisted-Pair Transmit Output (Negative)
The TPO- pin functions as the negative signal in the
twisted-pair output.
