Description
The miSLICTM Line Circuits together with
processor or SoC, provides an economical
solution for derived voice applications. The
devices are controlled by a VoIP processor
through a simple, single serial interface.
Manufacturing self test and subscriber line diagnostics
are available features. All AC, DC, and power parameters
are programmable making the Le9662 device suitable for
any short loop application requiring SLIC functionality.

miSLIC
or SoC
The dual channel Le9662 miSLIC device uses energy
efficient shared power supply topologies for reduced BOM
cost. The Le9662 can be configured for patent-pending
shared Buck-Boost Automatic Battery Switching (BBABS)
or for shared Flyback ABS (FBABS) operation. Ringing
and system power management are supported to limit the
peak power requirements of each telephone line FXS
port. The dual channel Le9662 features wideband clarity
and complete BORSCHT functionality.
Facilitates factory testing and calibration of
assembled boards
