Description

The innovative Le5711 dual-channel SLIC device is

designed for high-density POTS applications requiring

a small footprint SLIC device with significant power

savings. By combining the line interface of two

channels into one SLIC device, the Le5711 device

enables the design of a low cost, high performance,

and fully programmable line interface for multiple

country applications worldwide. The on-chip Thermal

Management (TMG) feature allows for significantly

reduced power dissipation on the device. The Le5711

device is offered in a space-saving package type, 44-

pin eTQFP. The small footprint of the SLIC device

allows designers to save board space, increasing the

density of lines on the board. The Le5711 device is

also designed to significantly reduce the number of

external components required for linecard design.

Zarlink offers a range of compatible codec/filters that

perform the codec function in a line card. In particular

the Zarlink QLSLAC™ device, another member of the

VE580 series, combined with the Le5711 device

provides a programmable line circuit that can be

configured for varying requirements.
