ITU Low Cost, PABX SLIC With 40mA
Loop Feed
The Intersil SLIC incorporates many of the BORSHT
functions on a single IC chip. This includes DC battery feed,
a ring relay driver, supervisory and hybrid functions. This
device is designed to maintain transmission performance in
the presence of externally induced longitudinal currents.
Using the unique Intersil dielectric isolation process, the
SLIC can operate directly with a wide range of station
battery voltages.
The SLIC also provides selective denial of power. If the PBX
system becomes overloaded during an emergency, the SLIC
will provide system protection by denying power to selected
subscriber loops.
The Intersil SLIC is ideally suited for the design of new digital
PBX systems by eliminating bulky hybrid transformers.

DESCRIPTION
26 C4 Capacitor #4 - An external capacitor to be connected between this terminal and analog ground. This capacitor prevents
false ground key indication and false ring trip detection from occurring when longitudinal currents are induced onto the
subscriber loop from near by power lines and other noise sources. This capacitor is also required for the proper operation
of ring trip detection. Typical value is 0.5µF, to 1.0µF, 20V. This capacitor should be nonpolarized.
27 AG Analog Ground - To be connected to zero potential and serves as a reference for the transmit output (TX) and receive
input (RX) terminals.
28 TX Transmit Output, Four Wire Side - A low impedance analog output which represents the differential voltage across Tip
and Ring. Transhybrid balancing must be performed (using the SLIC microcircuit’s spare op amp) beyond this output to
completely implement two to four wire conversion. This output is unbalanced and referenced to analog ground. Since the
DC level of this output varies with loop current, capacitive coupling to the next stage is essential.

NC No internal connection.
NOTE: All grounds (AG, BG, and DG) must be applied before VB+ or VB-. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.
