SI3210-FTR Datasheet

Telecom Line Management ICs


The SI3210-FTR ProSLIC® 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 . The CMOS ProSLIC interfaces to the line through either the Si3201 Line-feed IC or a discrete line-feed circuit. SI3210-FTR 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-FTR is packaged in a 38-pin QFN or TSSOP, and the Si3201 is packaged in a thermally-enhanced 16-pin SOIC.
