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
PK
,
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.
