DESCRIPTION
The innovative Le57D11 Dual Channel SLIC device was
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 Le57D11 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. Another benefit is that it is
offered in space-saving package types 44-pin eTQFP and 32-
pin PLCC. The small footprint of the SLIC device allows
designers to save board space, increasing the density of lines
on the board. The Le57D11 device is also designed to
significantly reduce the number of external components
required for line card design.
Legerity offers a range of compatible SLAC devices that
perform the codec function in a line card. In particular, the
Legerity Quad SLAC device combined with the Le57D11
device provides a programmable line circuit that can be
configured for varying requirements.
