Description
The miSLICTM 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.
Facilitates factory testing and calibration of
assembled boards
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.
