021/031 QSLAC™ device

Performs the functions of four codec/filters

Software programmable:

— SLIC device input impedance

— Transhybrid balance

2. For delivery using a tape and reel packing system, add a "T" suffix

to the OPN (Ordering Part Number) when placing an order.

DESCRIPTION

— Transmit and receive gains

— Equalization (frequency response)

— Digital I/O pins

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.

— Programmable debouncing on one input

— Time slot assigner

— Programmable clock slot and PCM transmit clock edge

options

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

— Optional supervision on the PCM highway

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.

1.536, 1.544, 2.048, 3.072, 3.088, 4.096, 6.144, 6.176, or

8.192 MHz master clock derived from MCLK or PCLK

Built-in test modes with loopback, tone generation,

and µP access to PCM data

Mixed state (analog and digital) impedance scaling

Performance guaranteed over a 12 dB gain range
