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.
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 consumption needed in linecard designs to maximize linecard density at minimum cost. When used with two AMD SLICs, the DSLAC device provides software configurable solutions to the BORSCHT function.
