MICROCHIP LE9642PQC

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 Le9642 miSLIC device uses an energy efficient shared power supply topology for reduced BOM cost. The Le9642 can be configured for patent-pending shared Buck-Boost Automatic Battery Switching (BBABS) operation. Ringing and system power management are supported to limit the peak power requirements of each telephone line FXS port. The dual channel Le9642 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 Le9642 device suitable for any short loop application requiring SLIC functionality.
