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 compatible 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 Legerit...
