Le9661

Overview

The miSLIC™ Line Circuits together with a VoIP processor or SoC, provide 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 Le9661 miSLIC 1 FXS tracking device is a drop-in, pin compatible, device to the miSLIC 2 FXS Le9662 FBABS or Le9672 Tracker devices. The Le9661 uses energy efficient power supply topologies for reduced BOM cost. The Le9661 can be configured to operate a flyback full tracking supply or an inverting buck-boost fixed tracking supply. Ringing and system power management are supported to limit the peak power requirements of the telephone line FXS port. The Le9661 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 miSLIC device suitable for any application requiring SLIC functionality.
