GENERAL DESCRIPTION

The Am79Q02/021/031 Quad Subscriber Line Audio-

Processing Circuit (QSLAC) devices integrate the key

functions of analog linecards into high-performance,

very-programmable, four-channel codec-filter devices.

The QSLAC devices are based on the proven design

of Legerity’s reliable SLAC™ device families. The

advanced ar chitecture of the Q SLAC devic es

implements four independent channels and employs

digital filters to allow software control of transmission,

thus providing a cost-effective solution for the audio-

processing function of programmable linecards.

Advanced submicron CMOS technology makes the

Am79Q02/021/031 QSLAC devices economical, with

both the functionality and the low power consumption

needed in linecard designs to maximize linecard

density at minimum cost. When used with four Legerity

SLICs, a QSLAC device provides a complete software-

configurable solution to the BORSCHT functions.
