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, very-

programmable, 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 Legerity SLIC devices, a QLSLAC device

provides a complete software-configurable solution to the

BORSCHT functions.

Standard microprocessor interface

A-law, µ-law, or linear coding

Single or Dual PCM ports available

— Up to 128 channels (PCLK at 8.192 MHz) per PCM port
