Dual Subscriber Line Audio Processing Circuit (DSLAC™) Devices

DISTINCTIVE CHARACTERISTICS

GENERAL DESCRIPTION

■ Software programmable:

— SLIC impedance

The Am79C02/03/031(A) Dual Subscriber Line Audio

Processing Circuit (DSLAC device) integrates the key

functions of an analog linecard into a single high-per-

formance, programmable dual codec/filter device. The

DSLAC device is based on the proven design of the

reliable Am7901A Subscriber Line Audio Processing

Circuit (SLAC^™device). The advanced architecture of

the DSLAC device implements two independent chan-

nels and employs digital filters to allow software control

of transmission, thus providing a cost effective solution

for the analog to PCM function of a linecard.

— Transhybrid balance

— Transmit and receive gains

— Equalization

— Digital I/O pins

— Time Slot Assigner

— PCM transmit clock edge options

■ Adaptive transhybrid balance filter

(A suffix only)

The Am79C02/03/031(A) DSLAC device’s advanced

CMOS technology makes this an economical device

that has both the functionality and the low power con-

sumption needed in linecard designs to maximize line-

card density at minimum cost. When used with two AMD

SLICs, the DSLAC device provides software config-

urable solutions to the BORSCHT function.

■ A-law or µ-law coding

■ Dual PCM ports

— Up to 8.192 MHz each (128 channels per port)

■ 2.048 MHz or 4.096 MHz master clock

■ Direct transformer drive

■ Built-in test modes

■ Low power CMOS

■ Mixed mode (analog and digital) impedance

scaling

■ Performance characteristics guaranteed over

12 dB gain range
