Notes:
1. TX Fault is an open collector output, which should be pulled up with a 4.7K~10K. 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 a 4.7K~10K. resistor. Its states are:
Low (0~0.8V) : Transmitter on
(>0.8V, <2.0V) : Undefined
High (2.0~3.465V) : Transmitter Disabled
Open : Transmitter Disabled.
3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7K~10K. 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~10K. 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 100. differential lines which should be
terminated with 100. (differential) at the user SERDES.
6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100.differential
termination inside the module.
