The Si324x Quad ProSLIC products offer high channel density and extensive features in the industry’s smallest footprint subscriber line interface circuit (SLIC). These innovative devices allow one hardware design to be deployed worldwide in enterprise and central office telecom applications.
The Quad ProSLIC are a series of low-voltage CMOS devices that integrate both SLIC and codec functionality into a single IC to provide a complete four-channel analog telephone interface in accordance with all relevant LSSGR, ITU, and ETSI specifications. The Si3241 includes internal ringing generation to eliminate centralized ringers and ringing relays. The Si3245 supports centralized ringing for long loop and legacy applications. On-chip subscriber loop and audio testing allows remote diagnostics and fault detection with no external test equipment or relays. The Quad ProSLIC devices operate from a single 3.3 V supply and interface to standard PCM/SPI or GCI bus digital interfaces. The Si3205 linefeed interface IC performs all high-voltage functions and operates from a 3.3 V supply as well as single or dual-battery supplies up to 150 V. The Quad ProSLIC devices are available in a 100-pin thin quad flat package (TQFP), and the Si3205 is available in a thermally enhanced 16-pin small outline (SOIC) package.
An application programming interface (API) is available to accelerate and simplify code development.
