Product Summary
The SI3215-FM is a proslic programmable CMOS SLIC/codec that provides a complete analog telephone interface ideal for customer premise equipment (CPE) applications. The SI3215-FM 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 (Si3215M only) or 5 V supply. The applications of the SI3215-FM include Voice-over-broadband systems: DSL, cable, wireless, PBX/IP-PBX/key telephone systems, Terminal adapters: ISDN, Ethernet, USB.
