Transmit Analog Positive Pulse (TAP).
This analog output drives an AC
signal through an external matching
transformer. It is connected to the
positive lead of the transformer
primary.
An analog Transmit Monitor Positive
point is internally bonded to this
output and is used to monitor the
positive pulses on the transmit line.
TAN
Transmit Analog Negative Pulse
(TAN). This analog output drives an
AC signal through an external
matching transformer. It is connected
to the negative lead of the transformer
primary.
An analog Transmit Monitor Negative
point is internally bonded to this
output and is used to monitor the
negative pulses on the transmit line.
TC
Transmit Reference Decoupling
Capacitor (TC). This analog
bidirectional provides decoupling for
an internal reference generator. It is
connected to a decoupling capacitor
to TAVD.
