Am79Q021 - Quad Subscriber Line Audio-Processing

Download the Am79Q021 datasheet PDF. This datasheet also covers the Am79Q02 variant, as both devices belong to the same quad subscriber line audio-processing family and are provided as variant models within a single manufacturer datasheet.

Description

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.
