The Si3210/11/15/30/33 ProSLIC family of subscriber line interface circuits (SLICs) provides a complete analog telephone interface ideal for customer premises equipment (CPE) applications. The Si3210/11/15/30/33 SLICs integrate the subscriber line interface circuit, codec and battery generation functionality into a single low-voltage CMOS IC. No other SLIC offers the combination of performance and small footprint.
Combined with Silicon Labs’ 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.
