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 (Si3210M/Si3211M

only) or 5 V supply. The ProSLIC controls the phone line through Silicon Labs’

Si3201 Linefeed Interface Chip. Si3210 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 and TSSOP, and

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