Name/Description
Module Ground
Optional -5.2V power supply (not used)
Module De-Select; when held low allows module to respond to 2-wire interface interface
Interrupt; indicates presence of an important condition which can be read over the 2-wire
serial interface
Transmitter Disable; turns off transmitter laser output
+5 V Power Supply
Module Ground
+3.3 V Power Supply

2-Wire Serial Interface Clock
2-Wire Serial Interface Data Line
Indicates module is not present. Grounded in the module
Module Not Ready; indicating module operational fault
Receiver Loss of Signal Indicator

+1.8 V Power Supply
Power Down; When high, requires the module to limit power consumption to 1.5 W or
below. 2-wire serial interface must be functional in the low power mode.
Reset; the falling edge initiates a complete rest of the module including the 2-wire serial
interface, equivalent to a power cycle.

Note:
1. Module ground pins GND are isolated from the module case and chassis ground within the module.
2. Shall be pulled up with 4.7k-10kohms to a voltage between 3.15 V and 3.45 V on the host board.
