HTPLG1 IN
Hot Plug Input
This pin is used to monitor the "HOT PLUG" signal for transmitter port 1. Note:
This input is only 3.3V tolerant and has no internal debouncer circuit.
EXT_SWING01 Analog Voltage Swing Adjust for Port 0/1. A resistor should tie this pin to AVDD. This
resistance determines the amplitude of the voltage swing.
