Notes:
1.
Connected directly to TX data input pins. AC coupled thereafter.
2.
Or open circuit.
3.
Into 100 ohms differential termination.
4.
20% to 80 %
5.
Loss Of Signal is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
6.
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.
