AM79Q021 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. Th advanced architecture of the QSLAC devices 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.
