Description

The HC5519 SLIC is designed to meet the technical require-

ments of the China Telecommunications network. It provides

many of the BORSCHT functions associated with a Central

Ofﬁce line circuit.

The HC5519 consists of an A-Law Codec/Filter, a 2-wire

interface circuit, an impedance control circuit, a ringing con-

trol circuit, a power management circuit, and a serial control

interface circuit which is used to program and monitor the

operation of the device.

The integration of the line interface and coder/decoder func-

tions into a 80 pin MQFP surface mount package and standard

value surface mount components avoids the need for costly

hybrid packaging techniques and offers the superior reliability of

an integrated solution for dense circuit board layouts.

The SLIC combines Harris’ patented Bonded Wafer

Dielectrically Isolated fabrication techniques with a state of

the art CMOS process to produce the world’s most compact

line circuit signal processing solution.
