1 / 118 page Rev. 0.92 8/05 Copyright © 2005 by Silicon Laboratories Si3215 Si3215 PROSLIC® PROGRAMMABLE CMOS SLIC/CODEC WITH RINGING/BATTERY VOLTAGE GENERATION Features Applications Description The ProSLIC is a low-voltage CMOS device that provides a complete analog telephone interface ideal for customer premise equipment (CPE) applications. The ProSLIC integrates subscriber line interface circuit (SLIC), codec, 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 (Si3215M only) or 5 V supply. The ProSLIC controls the phone line through Silicon Labs’ Si3201 Linefeed Interface Chip or discrete component line feed. Si3215 features include software-configurable 5 REN internal ringing up to 90 VPK, DTMF generation, and a comprehensive set of telephony signaling capabilities including expanded support of Japan and China country requirements. The ProSLIC is packaged in a 38-pin QFN and TSSOP, and the Si3201 is packaged in a thermally-enhanced 16- pin SOIC.
