Description

The miSLIC

Series Line Circuits together with a VoIP

processor or SoC, provides an economical turn-key

solution for derived voice applications. The versatile

Le9641 miSLIC can be controlled via a PCM/SPI or ZSI

interface.

The Le9641 miSLIC 1 FXS Tracking device is a drop-in

pin compatible device to the miSLIC 2 FXS Le9642

device. The Le9641 uses energy efficient power supply

topologies for reduced BOM cost. The Le9641 can be

configured to operate a Buck-Boost fixed tracking supply

or an Inverting-Boost supply. Ringing and system power

management are supported to limit the peak power

requirements of the telephone line FXS port. The Le9641

features wideband clarity and complete BORSCHT

functionality.

Manufacturing self test and subscriber line diagnostics

are available features. All AC, DC, and power parameters

are programmable making the Le9641 device suitable for

any short loop application requiring SLIC functionality.
