TPB0
Analog I/O
Portn, Port Cable Pair B.
TPBn is the port B connection to the twisted-
pair cable. Board traces from each pair of positive and negative differen-
tial signal pins should be kept matched and as short as possible to the
external load resistors and to the cable connector.
Analog I/O
Portn, Twisted-Pair Bias.
TPBIAS provides the 1.86 V nominal bias
voltage needed for proper operation of the twisted-pair cable drivers and
receivers and for sending a valid cable connection signal to the remote
nodes.

XI and XO connect to a 24.576 MHz parallel resonant
fundamental mode crystal. Although, when a 24.576 MHz clock source is
used, it can be connected to XI with XO left unconnected. The optimum
values for the external shunt capacitors are dependent on the specifica-
tions of the crystal used. For more details, see Crystal Selection Consider-
ations in the Application Information section.
