Pin-out Table
The pin arrangement and definition of this product meets SFP MSA. Table 2 lists the pin description.
Table 2 - Pin description
Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10K resistor on the host board. Pull up voltage
2. TX Disable input is used to shut down the laser output per the state table below with an external 4.7 - 10 KΩ pull-up resistor.
3. MOD-DEF 0,1,2. These are the module definition pins. They should be pulled up with a 4.7 - 10 KΩ resistor on the host board to a supply
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7K - 10 KΩ resistor on the host board
5. RD-/+: These are the differential receiver outputs. They are ac coupled 100Ω differential lines which should be terminated with 100Ω
6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.135 - 3.465 V at the SFP connector pin. The
7. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100Ω differential termination inside the

to a supply < VccT,R+0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as
defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V.
differential at the user SERDES. The ac coupling is done inside the module and is thus not required on the host board. The voltage swing
on these lines will be between 370 and 1600 mV differential (185 - 800 mV single ended) when properly terminated.
maximum supply current is 300 mA and the associated inrush current will be no more than 30 mA above steady state after 500
nanoseconds.
module. The ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of
500 - 2400 mV (250 - 1000 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 - 600 mV
single ended) be used for best EMI performance.
