Notes:
1. TX_FAULT is an open collector/drain output, which must be pulled up with a 4.7 k – 10 kΩ resistor on the host board. When high, this output
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 6.8 kΩ
Low (0 – 0.8 V ):
Between (0.8 V and 2.0 V ):
High (2.0 – Vcc max) or OPEN:
3. The signals Mod-Def 0, 1, 2 designate the two wire serial interface pins. They must be pulled up with a 4.7 k – 10 kΩ 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 4.7 k – 10 kΩ resistor on the host board. When high,
5. RD-/+ designate the differential receiver outputs. They are AC coupled 100 Ω differential lines which should be terminated with 100 Ω differ-
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
7. TD-/+ designate the differential transmitter inputs. They are AC coupled differential lines with 100 Ω differential termination inside the module.
indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V .
resistor.
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 .
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.
mA and the associated in-rush current will typically be no more than 30 mA above steady state after 2 microseconds.
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 – 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.
