1. TX_FAULT is an open collector/drain output, which must be pulled up with a 4.7k – 10kΩ resistor on the host board. When high, this output

indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.

2. TX_DISABLE is an input that is used to shut down the transmitter optical output. It is internally pulled up (within the transceiver) with a 6.8kΩ

resistor.

Low (0 – 0.8V):

Between (0.8V and 2.0V):

High (2.0 – Vcc max) or OPEN:

Transmitter on

Undeﬁned

Transmitter Disabled

3. The signals Mod-Def 0, 1, 2 designate the two wire serial interface pins. They must be pulled up with a 4.7k – 10kΩ resistor on the host board.

Mod-Def 0 is grounded by the module to indicate the module is present

Mod-Def 1 is serial clock line (SCL) of two wire serial interface

Mod-Def 2 is serial data line (SDA) of two wire serial interface

4. RX_LOS (Rx Loss of Signal) is an open collector/drain output that must be pulled up with a 4.7k – 10kΩ resistor on the host board. 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 < 0.8V.

5. RD-/+ designate the diﬀerential receiver outputs. They are AC coupled 100Ω diﬀerential lines which should be terminated with 100Ω diﬀer-

ential at the host SERDES input. AC coupling is done inside the transceiver and is not required on the host board. The voltage swing on these

lines will be between 600 and 1600 mV diﬀerential (300 – 800 mV single ended) when properly terminated.

6. VccR and VccT are the receiver and transmitter power supplies. They are deﬁned at the SFP connector pin. The maximum supply current is 300

mA and the associated in-rush current will typically be no more than 30 mA above steady state after 2 microseconds.

7. TD-/+ designate the diﬀerential transmitter inputs. They are AC coupled diﬀerential lines with 100 Ω diﬀerential termination inside the module.

The AC coupling is done inside the module and is not required on the host board. The inputs will accept diﬀerential swings of 400 – 2400 mV

(200 – 1200mV 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.
