Description

The Si3210/11 ProSLICÂ® chipset provides a complete analog telephone interface ideal

for customer premise equipment (CPE). It integrates a subscriber line interface circuit

(SLIC), voice codec, and battery generation (Si3210) or battery selection (Si3211) into

a single CMOS integrated circuit. The battery supply continuously adapts its output

voltage to minimize power dissipation and enables the entire circuit to be powered

from a single 3.3 or 5 V supply (Si3210). The CMOS ProSLIC interfaces to the line

through either the Si3201 Line-feed IC or a discrete line-feed circuit.

Si3210/11 features include software-configurable 5 REN internal ringing up to 90 VPK,

DTMF generation and decoding, Caller ID generation, and a comprehensive set of

telephony signaling capabilities for global operation with a single hardware solution.

The Si3210/11 is packaged in a 38-pin QFN or TSSOP, and the Si3201 is packaged in

a thermally-enhanced 16-pin SOIC.
