Pin Descriptions Notes:

 

Plug Seq.: Pin engagement sequence during hot plugging.

 

1) TX Fault 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 a laser fault of some kind. In the low state, the output will be pulled to less than 0.8V.

 

2) TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a4.7k~10kΩ resistor. Its states are:

 

Low (0 to 0.8V): Transmitter on

(>0.8V, < 2.0V): Undefined

 

High (2.0 to 3.465V): Transmitter Disabled

Open: Transmitter Disabled

 

3) Mod-Def. 0, 1,2. These 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 grounded by the module to indicate that the module is present

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) LOS is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor. Pull up voltage between 2.0V andVccand0.3V. Logic 1 indicates loss of signal; Logic 0 indicates normal operation. In the low state, the output will be pulled to less than 0.8V.

 

5) RD-/+: These are the differential receiver outputs. They are internally AC-coupled 100 differential lines which should be terminated with 100Ω (differential) at the user SERDES.

 

6) TD-/+: These are the differential transmitter inputs. They are internally AC-coupled, differential lines with 100Ω differential termination inside the module.
