Infineon PEB3264-0HV1.4

IN FIN E O N'S Du S LIC (Dual Channel Subscriber Line Interface Concept) chipset provides a two-channel POTS interface optimized for Customer Premise Equipment and Access Network applications, both in standard telephony and in Voice over Packet technology. The fully programmable Du SLIC chipset provides optimum voice and modem transmission performance, extremely low power consumption, and a comprehensive set of new system features such as DTMF, echo cancellation, integrated ringing and line testing. It consists of a two-channel codec-filter with enhanced functionality (with or without enhanced feature set) and either two single-channel SLiCs or one dual-channel TSLiC.

• Optimized for VoDSL, VolP, VoATM and VoCable
• Integrated DTMF receiver, CLIP generation, metering pulses, etc.
• Integrated line echo cancellation (8 ms)
• Ring generation (balanced and unbalanced) integrated
• Lowest power for lifeline support
• Echo Cancellation needed to avoid bad voice quality in packet-based networks
• Easy-to-use and available solutions necessary to speed time-to-market; SW and HW available
• Modem-performance at V.9o transmission for maximum speed
• Compatibility to existing POTS solutions
• Strong price/performance ratio
• Voice (Ac) impedances and levels programmable
• Feeding current, ring-trip, loop length programmable
• Ring voltage, offset, balanced/unbalanced programmable; ringing integrated, no relays
• DTMF reciever and transmitter (touchtone), tone generation, metering (TTX), CLIP as DTMF/FSK integrated and programmable
• Low power consumption. At least one phone line working from remote feeding to cover emergency situations
• Power management offering full performance in normal situation, and full control in lifeline mode
• Remote line testing of short-circuits, foreign-voltage, capacitance, resistance, etc. to eliminate service visits to individual sites
• No extensive final factory testing necessary due to self-test capability
• DTMF receiver, tone generator, CLiP generator, echo-cancellation integrated in codec device without external components offers high integration, cost effective solutions and optimum performance
• All AC, DC and ring parameters SW programmable on same HW platform with optimized filter structures allowing for no need for external RAM, ring generator, relays etc., worldwide standard requirements and optimized voice and V.9o performance
• Lowest drop voltages available in the market along with enhanced power management supply
• Lifeline supported 13.3 V SLICs allow for complete 3.3 V power supply designs
• Calculating line behavior through integrated measurement of voltages, currents, and tones help to enable enhanced QoS, no additional costs, more safety and comfort for customers

• IAD/Cable Modem Applications
• ISDN Applications, e.g. intelligent NT
