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.
