1. TX Fault is not used and tied to ground within the module.

2. TX Disable is not used and is not connected within the module.

3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10kΩ resistor on the host board. The pull-up voltage shall be VccT or VccR.

MOD-DEF 0 is tied to ground within the module.

MOD-DEF 1 is the clock line of two wire serial interface for serial ID

MOD-DEF 2 is the data line of two wire serial interface for serial ID

4. The LOS will be LVTTL low for link ok and will be LVTTL high for link off. Externally pull up to VccR or VccT with 4.7k – 10k ohm on host board.

5. These are the differential receiver output. Internally AC-coupled in the transceiver. 100Ω differential lines and 100 Ω terminate resistor should be used on the host board.

6. VccT and VccR are internally connected together in the transceiver.

7. These are the differential receiver input. Internally AC-coupled in the transceiver. 100Ω differential lines and 100 Ω terminate resistor is used in the transceiver.
