Its characteristics and specifications are subject to change without notice. Si3230 PROSLIC® PROGRAMMABLE CMOS SLIC WITH RINGING/BATTERY VOLTAGE GENERATION Features Applications Description The Si3230 ProSLIC® is a low-voltage CMOS device that provides a multi-functional subscriber line interface ideal for customer premise equipment (CPE) applications. The ProSLIC integrates subscriber line interface circuit (SLIC) and battery generation functionality into a single CMOS integrated circuit. The integrated battery supply continuously adapts its output voltage to minimize power and enables the entire solution to be powered from a single 3.3 V (Si3230M only) or 5 V supply. The ProSLIC controls the phone line through Silicon Labs’ Si3201 Linefeed IC or discrete circuitry. Si3230 features include software-configurable 5 REN internal ringing up to 90 VPK, DTMF generation and decoding, and a comprehensive set of telephony signaling capabilities for operation with only one hardware solution. The ProSLIC is packaged in a 38-pin QFN or TSSOP, and the Si3201 is packaged in a thermally-enhanced 16-pin SOIC.
