The Si3210 ProSLIC provides a complete analog telephone interface ideal for customer premise equipment (CPE) applications. The Si3210 integrates subscriber line interface circuit (SLIC), codec and battery generation functionality into a single low-voltage CMOS integrated circuit.
Combined with Silicon Laboratories’ Si3201 linefeed integrated circuit, the Si3210 packs maximum performance and flexibility into a 1.5 in² footprint, making it the smallest single-channel telephony interface available. 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 or 5 V supply. Software configurable features include 5 REN internal ringing up to 90 VPK, DTMF generation and decoding, and a comprehensive set of telephony signaling capabilities for global operation with only one hardware solution. The Si3230 provides the same performance of the Si3210 without the integrated codec.
An application programming interface (API) is available to accelerate and simplify code development.
