Single chip CODEC and FILTER including all

LOW-VOLTAGE SLIC functions.

Advanced 12V BJT, 5V CMOS 0.8um technol-

ogy.

Low external component count.

Over-sampling A/D and D/A conversion.

No functional trimming or adjustments re-

quired.

Serves a wide range of specifications; i.e. ITU-

T, LSSGR.

A-law, and -law PCM and Linear voice cod-

ing, sw selectable

GCI compatible interface.

Programmable Digital-Filters for impedance-

matching, hybrid-balance, frequency-response

and gain.

Programmable Feeding-Resistance (2 x 50

to 2 x 400 ) and current-limiting (0-69.3mA).

Programmable

transmission needs.

12kHz/16kHz Teletax Generation with Pro-

grammable Level 0-10 Vrms in 40mV steps in-

cluding shaping and filtering.

Integrated Ring-Generator with Zero-Crossing.

Programmable frequency from 16.6Hz to

60Hz, programmable level up to 85Vrms, Inte-

grated auto ring-trip.

Signalling functions ON/OFF - Hook, Gnd-key

with filter and Programmable persistence

check.

Advanced test capabilities:

On-board line tests and circuit tests.

Signalling tests for meterpulse TTX and Ring-

ing.

Tone generator for circuit test.

3 Loop-back paths.

Three operating conditions:

Power Down, Active, Ringing. Off-hook pro-

grammable threshold-level in each of these

conditions.

Interface to High-Voltage SLIC to select

modes, provide hard or soft Polarity-Reversal

and sense HV (L3000N, L3000S, STLC3170)

High Thermal condition.

On-hook transmission capability.

Selectable 2/4MHz backplane clock.

Standard PLCC 44 package.

DESCRIPTION

The subscriber line codec-filter, STLC3040, is

fabricated in BiCMOS (12V bipolar / 5V CMOS)

technology.

ing(DSP) to implement central-office telephone in-

terface features: DC-feed, Supervision, PCM-

Codec-Filter, Ring, Teletax metering (TTX) and

Test functions. The STLC3040 is fully program-

mable and needs few external resistors and ca-

pacitors.

The STLC3040 interfaces the subscriber’s line via

the

STLC3170) device and the central-office back-
