PTG
Programmable Transmit Gain - The 2-wire to 4-wire transmission gain is 0dB if this pin is left floating
and -6.02dB if tied to ground. The -6.02dB gain option is useful in systems where Pulse Metering is
used. See Figure 23.

ZT
2-Wire Impedance Matching Pin - Impedance matching of the 2-wire side is accomplished by placing
an impedance between the ZT pin and ground. See Equation 32.

RDC_RAC
Resistive Feed/Anti Clipping - Performs anti clipping function on constant current application and sets
the slope of the resistive feed curve for constant voltage applications.

CRT_REV
_LVM
Ring Trip, Soft Polarity Reversal and Line Voltage Measurement - A capacitor when placed between the
CRT_REV_LVM pin and +5V performs 3 mutually exclusive functions. When the SLIC is configured in the
Ringingmodeitprovidesfilteringoftheringingsignaltopreventfalsedetect.WhentheSLICistransitioning

CDC
Filter Capacitor- The CDC Capacitor removes the VF signals from the battery feed control loop.

DT
Tip side of Ring Trip Detector - Ring trip detection is accomplished by connecting an external network
to a detector in the SLIC with inputs DT and DR. Ring trip occurs when the voltage on DT is more
negative than the voltage on DR.

DR
Ring Side of Ring Trip Detector - Ring trip detection is accomplished by connecting an external
network to a detector in the SLIC with inputs DT and DR. Ring trip occurs when the voltage on DR is
more positive than the voltage on DT.
