MOD_DEF(0) pulls line low to indicate module is plugged in.
4. Receiver achieves multi-rate operation 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
5.5V.
Logic 0 indicates normal operation; logic 1 indicates loss of signal.

Loss of signal (LOS) is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified
value applied through the recommended power supply filtering network.
