Note:

1.     TX Fault is open collector output which should be pulled up externally with a 4.7K ~10KΩ resistor   on the host board to voltage between 2.0V and V_CC+0.3V. Logic 0 indicates normal operation; logic 1 indicates a laser fault of some kind. In the low state, the output will be pulled to less than 0.8V.

2.     TX Disable input is used to shut down the laser output per the state table below. It is pulled up within the module with a 4.7~ 10K resistor.

    Low (0- 0.8V):                          Transmitter on

    Between (0.8V and 2V):      Undefined

    High (2.0 – VccT):                      Transmitter Disabled

3.     MOD-DEF 0, 1, 2. These are the module definition pins. They should be pulled up with a 4.7~10K resistor on the host board to supply less than VccT+0.3V or VccR+0.3V.

MOD-DEF 0 is grounded by the module to indicate that the module is present.

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

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

4.     LOS (Loss of signal) is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. In the low state, the output will be pulled to less than 0.8V.

5.     These are the differential receiver outputs. They are AC-coupled 100Ω differential lines which should be terminated with 100Ω differential at the user SERDES. The AC coupling is done inside the module and thus not required on the host board.

6.     These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module.
