LE9652PQC [Microchip]

The miSLIC™ Series Subscriber Line Interface Circuit together with a VoIP processor or SoC, provides an economical turn-key solution for derived voice applications. The miSLIC device is controlled by a VoIP processor or SoC through a simple, single serial interface. The dual channel Le9652 miSLIC device uses individual Tracking power supplies capable of ringing up to 140 Vpk with high efficiency to minimize power dissipation in all states. Ringing and system power management are supported to limit the peak power requirements of the telephone line FXS port. The Le9652 features wideband clarity and complete BORSCHT functionality. Manufacturing test and subscriber line testing are standard features. All AC, DC, and power parameters are programmable making the Le9652 device suitable for any application requiring SLIC functionality.
