Microchip's cost-effective, software-programmable solution is the Le58QL02/021/031 QLSLAC and the Le58QL061/063 QLSLAC line of DSP-based voice codec/filters. The four-channel QLSLAC devices handle the analog-to-digital and digital-to-analog conversion, filtering, compression and expansion functions required to interface a telephone's analog voice signals to the digital PCM highway or General Circuit Interface (GCI).

The Le58QL022 Quad Low Voltage Subscriber Line Audio-Processing Circuit (QLSLAC™) devices integrate the key functions of analog line cards into high-performance, veryprogrammable, four-channel codec-filter devices. The QLSLAC devices are based on the proven design of Legerity’s reliable SLAC™ device families. The advanced architecture of the QLSLAC 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 line cards. The QLSLAC devices are software and coefficient compatible to the QSLAC devices.
