LE57D111 PRODUCT PROFILE - 34456 Dual Subscriber Line Interface Circuit Le5711

A Voice Solution

VE580 Series

APPLICATIONS DESCRIPTION

Ideal for low cost, high performance linecard applications (CO, DLC) The innovative Le5711 dual-channel SLIC device is designedfor high-density POTS applications requiring a small footprintSLIC device with significant power savings. By combining theline interface of two channels into one SLIC device, the Le5711 device enables the design of a low cost, high performance, andfully programmable line interface for multiple countryapplications worldwide. The on-chip Thermal Management (TMG) feature allows for significantly reduced powerdissipation on the device. The Le5711 device is offered inspace-saving package types, 44-pin eTQFP and 32-pin PLCC. The small footprint of the SLIC device allows designers to saveboard space, increasing the density of lines on the board. TheLe5711 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 performthe codec function in a line card. In particular the LegerityQLSLAC™ device, another member of the VE580 series,combined with the Le5711 device provides a programmableline circuit that can be configured for varying requirements. Meets requirements for countries such as: China, Korea, Japan, Taiwan, and Australia Fulfills the following China specifications: GF002-9002.1
