General Description

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-performance, 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 channels 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.
