SFP SeriesNotes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor
on the host board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates alaser fault of some kind. Low indicates normal operation. In the low state, the output will be pulledto < 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 4.7 – 10 K Ω resistor. Its states are:Low (0 – 0.8V): Transmitter on(>0.8, < 2.0V): UndefinedHigh (2.0 – 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 –10Kωresistor on the host board. The pull-up voltage shall be VccT or VccR (see Section IV for
further details). Mod-Def 0 is grounded by the module to indicate that the module is present ModDef 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 ID4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K –10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicatesthe received optical power is below the worst-case receiver sensitivity (as defined by the standardin use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
5) VeeR and VeeT may be internally connected within the SFP module.
6) RD-/+: 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 is thus not required on the host board. The voltage swing on these lines will
be between 370 and 2000 mV differential (185 –1000 mV single ended) when properly terminated.
7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5%
at the SFP connector pin. Maximum supply current is 300mA. Recommended host board power
supply filtering is shown below. Inductors with DC resistance of less than 1 ohm should be used inorder to maintain the required voltage at the SFP input pin with 3.3V supply voltage. When therecommended supply-filtering network is used, hot plugging of the SFP transceiver module will
result in an inrush current of no more than 30mA greater than the steady state value. VccR andVccT may be internally connected within the SFP transceiver module.
8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with100Ω differential termination inside the module. The AC coupling is done inside the module and isthus not required on the host board. The inputs will accept differential swings of 500 – 2400 mV(250 – 1200mV single-ended), though it is recommended that values between 500 and 1200 mV
differential (250 – 600mV single-ended) be used for best EMI performance.
