Notes:

1. Circuit ground is internally isolated from chassis ground.
2. TFAULTis an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the host board if intended

for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a transmitter fault caused by either the TX bias

current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the
output is pulled to 2.0V or open, enabled on TDIS<0.8V.
4. Should be pulled up with 4.7k - 10 kohms on host board to a voltage between 2.0V and 3.6V.

MOD_DEF(0) pulls line low to indicate module is plugged in.
5. LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage between 2.0V and 3.6V. Logic 0

indicates normal operation; logic 1 indicates loss of signal.
