NOTES:
1. TX FAULT is an open collector output that is pulled up with a 4.7 K - 10 K W resistor on the host board. Use
2. TX DISABLE is an input used to shut down the transmitter optical output. It is pulled up within the
3. MOD-DEF 0, 1, 2: These pins are definition pins for the TXN31115D2 Optical Transceiver. They are pulled
4. RATE SELECT: This signal function is not implemented in the TXN31115D2 Optical Transceiver. The
5. LOS (Loss of Signal) is an open collector output that is pulled up with a 4.7K – 10KW resistor on the host

(as defined by the standard in use).
Low: Indicates normal operation. In the low state, the output is pulled to < 0.8 V.
High: Indicates a laser fault.
Low (0 - 0.6 V): Transmitter Enabled
(>0.8, <2.0 V): Undefined
High (2.0 - 3.465 V): Transmitter Disabled
MOD-DEF 0 is grounded by the TXN31115D2 Optical Transceiver to indicate the TXN31115D2 Optical
MOD-DEF 1 is the clock line of a two-wire serial interface for serial ID.
MOD-DEF 2 is the data line of a two-wire serial interface for serial ID.
When low, this output indicates normal operation. In the low state, the output is pulled to < 0.8V.
When high, this output indicates the received optical power is below the worst-case receiver sensitivity
