Si3230

Notes:
1. Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation should be restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2. Operation above 125 oC junction temperature may degrade device reliability.
3. Thermal resistance assumes a multi-layer PCB with the exposed pad soldered to a topside PCB pad.

The Si3230 ProSLIC® is a low-voltage CMOS device that provides a multi-functional subscriber line interface ideal for customer premise equipment (CPE) applications. The ProSLIC integrates subscriber line interface circuit (SLIC) 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 (Si3230M only) or 5 V supply. The ProSLIC controls the phone line through Silicon Labs' Si3201 Linefeed IC or discrete circuitry. Si3230 features include software-configurable 5 REN internal ringing up to 90 VPK, DTMF generation and decoding, and a comprehensive set of telephony signaling  capabilities for operation with only one hardware solution. The ProSLIC is packaged in a 38-pin QFN or TSSOP, and the Si3201 is packaged in a thermally-enhanced 16-pin SOIC
