A.2 TP Transmit Interface
The interface between the TP outputs on TPO and the twisted pair
cable is typically transformer coupled and terminated with the two
resistors as shown in
The transformer for the transmitter should have a winding ratio of 1:1 with
a center tap on the primary winding tied to V
through

2. RJ-45 connector with integrated magnetics and LEDs
The transmit output must be terminated with two external termination
resistors to meet the output impedance and return loss requirements of
