Line Interface Circuits (SLIC)

Description

The HC4P5509A1R3060 telephone Subscriber Line
Interface Circuit integrates most of the BORSCHT functions
on a monolithic IC. The device is manufactured in a
Dielectric Isolation (DI) process and is designed for use as a
high voltage interface between the traditional telephone
subscriber pair (Tip and Ring) and the low voltage filtering
and coding/decoding functions of the line card. Together with
a secondary protection diode bridge and “feed” resistors, the
device will withstand 1000V lightning induced surges, in
plastic packages. The SLIC also maintains specified
transmission performance in the presence of externally
induced longitudinal currents. The BORSCHT functions that
the SLIC provides are:

• Battery Feed with Subscriber Loop Current Limiting

• Overvoltage Protection

• Ring Relay Driver

• Supervisory Signaling Functions

• Hybrid Functions (with External Op Amp)

• Test (or Battery Reversal) Relay Driver

In addition, the SLIC provides selective denial of power to
subscriber loops, a programmable subscriber loop current
limit from 20mA to 60mA, a thermal shutdown with an alarm
output and line fault protection. Switch hook detection, ring
trip detection and ground key detection functions are also
incorporated in the SLIC device.

The HC4P5509A1R3060 SLIC is ideally suited for line card
designs in PBX and CO systems, replacing traditional
transformer solutions.
