Description
The Si3210/11
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.
