DESCRIPTION The Le58QL02/021/031 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 patible to the QSLAC devices. Advanced submicron CMOS technology makes the Le58QL02/ 021/031 QLSLAC devices economical, with both the functionality and the low power consumption needed in line card designs to maximize line card density at minimum cost. When used with four...
