Notes:

1.

Circuit ground is internally isolated from chassis ground.

2.

3.

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.

4.

This transceiver operates between 1.25 and 3.07 Gb/s without active control.

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.
