Table 2. Pin Description
Notes:
1. TX_FAULT is an open collector/drain output, which should be pulled up with a 4.7 k – 10 kW 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 pulled up within the transceiver with a 4.7 k – 10 kW resistor.
3. The signals Mod-Def 0, 1, 2 designate the two wire serial interface pins. They should be pulled up with a 4.7 k – 10 kW resistor on the host board.
4. RX_LOS (Rx Loss of Signal) is an open collector/drain output that should be pulled up with a 4.7 k – 10 kW resistor on the host board. When high, this
5. RD-/+ designate the differential receiver outputs. They are ac coupled 100 W differential lines which should be terminated with 100 W differential at
6. V
7. TD-/+ designate the differential transmitter inputs. They are ac coupled differential lines with 100 W differential termination inside the module. The

450 and 2000 mV differential (225 – 1000 mV single ended) when properly terminated.
and the associated inrush current will typically be no more than 30 mA above steady state after 500 nanoseconds.
ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 350 – 2400 mV (175 –
1200 mV single ended).
