The miSLIC™ Line Circuits together with a VoIP processor or SoC, provides an economical turn-key solution for derived voice applications. The versatile Le9651 miSLIC device can be controlled via a PCM/SPI or ZSI interface. The Le9651 miSLIC 1 FXS tracking device is a drop-in, pin compatible, device to the miSLIC 2 FXS Le9652 device when using the ZSI interface. Tracking battery architectures are supported with ringing capability up to 140-Vpk. The supply is highly efficient and minimizes 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 Le9651 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.
