The Am79Q02/021/031 Quad Subscriber Line AudioProcessing 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 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 audioprocessing function of programmable linecards.
