Description

The Quad ProSLIC

devices that integrate both SLIC and codec

functionality into a single IC to provide a complete

four-channel

accordance with all relevant Telcordia, ITU, and ETSI

specifications. The Si3241 includes internal ringing

generation to eliminate centralized ringers and

ringing relays. On-chip subscriber loop and audio

testing allows remote diagnostics and fault detection

with no external test equipment or relays. The Quad

ProSLIC devices operate from a single 3.3 V supply

and interface to standard PCM/SPI or GCI bus digital

interfaces. The Si3206/3 linefeed interface IC

performs all high-voltage functions and operates

from a 3.3 V supply as well as three battery supplies

up to –135/–110 V. The Quad ProSLIC devices are

available in a 100-pin thin quad flat package (TQFP),

and the Si3206/3 is available in a thermally-

enhanced 48-pin thin quad flat package (TQFP) or

40-pin quad flat no-lead (QFN) package.

Features

- Performs all BORSCHT functions

- Ideal for applications up to 20 kft (6 km)

- Internal adaptive balanced ringing to
