Product Information

Back to top
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’ new 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 Si3210 is packaged in a 38-pin TSSOP, and the Si3201 is packaged in a thermally-enhanced 16-pin SOIC.

Applications:
• Fixed Wireless (cellular) Terminals
• Terminal Adapters
• PBX/IP-PBX/Key telephone systems
• Voice-over-IP Systems:
- DSL/EMTAs/FTTx
- WiMax/LTE
