Notes:
1. Tx Fault is an open collector/drain output which should be pulled up externally with a 4.7 K – 10 K
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 K – 10 K resistor.
3. Mod-Def 0,1,2. are the module definition pins. They should be pulled up with a 4.7 K – 10 K
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 K – 10 K

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 400 and 2000 mV differential (200 – 1000 mV single ended) when properly terminated.
current is 200 mA and the associated in-rush current will typically be no more than 30 mA above steady state after 500 nanoseconds.
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 – 1200 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. These levels are compatible with CML and LVPECL voltage swings.
