Connect to +3.3V power supply.
Connect to power supply ground.
Differential serial data input pair.
Differential serial data output pair.
Cable length indicator:
Analog voltage can be used to indicate the length of the cable
being equalized; this gives an indication of the amount of
equalization being applied. A higher output voltage results
from more compensation being used to recover the signal.
Leave unconnected when not used.
Carrier detect with light emitting diode driver.
High means a valid input signal, and SDOp/SDOn are turned on.
Low means no RX signal or the signal is too low, and SDOp/
SDOn are muted.
This pin can source up to 3 mA to directly drive an LED.
Leave unconnected when not in use.
Leave unconnected.
