Description
The miSLICTM Line Circuits together with a VoIP
processor or SoC, provides an economical turn-key
solution for derived voice applications. The miSLIC
devices are controlled by a VoIP processor or SoC
through a simple, single serial interface.
The dual channel Le9672 miSLIC device uses
individual Tracking Battery power supplies capable of
up to 140-VPK high voltage ringing combined with high
efficiency to minimize power dissipation in all states.
The dual channel Le9672 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 Le9672
device suitable for any application requiring SLIC
functionality.
