It integrates a subscriber line interface circuit 21 STIPDC 11 IRINGN SRINGDC 12 20 IGMP 13 14 15 16 17 18 19 (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. U.S. Patent 6,567,521 The Si3210/11 is packaged in a 38-pin QFN or TSSOP, and the Si3201 is packaged in U.S. Patent 6,812,744 a thermally-enhanced 16-pin SOIC.
