DESCRIPTION
The innovative Le5712 dual-channel SLIC device is designed
for high-density POTS applications requiring a small-footprint,
low-power SLIC device. By combining a fully featured line
interface of two channels into one SLIC device, the Le5712
device enables the design of a low-cost, high performance, and
fully programmable line interface for multiple country
applications worldwide, including Ground Start and metering
capability. The on-chip Thermal Management (TMG) feature
allows for significantly reduced power dissipation on the
device. Optional dual battery operation to reduce total power
consumption is also available. The device is offered in a
thermally efficient, space-saving 44-pin eTQFP package. The
12 x 12 mm footprint allows designers to make a dramatic
increase in the density of lines on a board. The Le5712 device
is also designed to significantly reduce the number of external
components required for line card design.
Zarlink offers a range of compatible SLAC™ devices that
perform the codec function in a line card. In particular, the
Legerity Quad and Octal SLAC devices combined with the
Le5712 device provides a programmable line circuit that can
be configured for varying requirements.
