Description

The Si3233 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 (Si3233M only) or 5 V supply. The ProSLIC

controls the phone line through Silicon Labs’ Si3201 Linefeed IC or discrete circuitry.

Si3233 features include software-configurable 5 REN internal ringing up to 90 V

DTMF generation, and a comprehensive set of telephony signaling capabilities for

operation with only one hardware solution. The ProSLIC is packaged in a 38-pin QFN

and the Si3201 is packaged in a thermally-enhanced 16-pin SOIC.
