The IA3223 and IA3222 integrated V.92 (56K) capable Data Access Arrangement (DAA) chipset is suitable for worldwide telephone line interface requirements and standards. The patented IsoBridge™ isolation technology eliminates the need for usual telecom isolation components, such as transformers or optocouplers. Innovative techniques reduce the overall number of discrete components, thus reducing the cost of the overall function.

The chipset can be programmed by software to pass PTT certification worldwide. The integrated V.92 EZ DAA™ offers an easy-to-use analog interface with an internal or external DC reference for interfacing to a variety of systems seamlessly. It allows easy building-block integration where audio codecs are either separate or integrated into DSPs. It is also ideal for non-modem systems requiring isolated DAAs, such as alarm systems, VoIP and PBX FXO interfaces, etc.
