boxes held to the same potential, and the cable shield might be depended upon to make that electrical con-
nection. Generally, it is a good idea to provide the option of grounding or capacitively coupling the shield to
the chassis.
The input signals to the RX, RXP, and RXN pins in all modes of operation are limited to amplitudes equal
to, or less than +3.3 V. In some cases it may be necessary to attenuate the input signal so the input to the
device is within the valid operating range.
