Notes:

1.Circuit ground is internally isolated from chassis ground.

2.TFAULT is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the host board. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates an LED fault, i.e. LED open or short. Low indicates normal operation. In the low state, the output is pulled to <0.8V.

3.LED output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.

4.Should be pulled up with 4.7k – 10kohms 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 – 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
