The IA3211/12 Optical Silicon DAA chipset consists of an IA3211 modem side integrated circuit and an IA3212 line side integrated circuit. Configured along with other components, the final circuit provides a full featured Optical Silicon DAA offering a turnkey solution for most modem applications.

All of the components in the chipset are packaged in easy to assemble, surface mount format. The IA3211 and IA3212 come in a standard 24-pin TSSOP package. A complete DAA circuit can be assembled directly onto a motherboard using less than 2 square inches of board space, eliminating costly special or hand-insert operations.

The IA3211 and IA3212 chipset is a full-featured Optical DAA that takes into consideration the needs of today’s portable and multimedia equipment. Added features of the IA3211 and IA3212 chipset such as line current sense, snooping and line V/F make the circuit ideal for enhanced modems, which support speakerphones, answering machines, simultaneous voice and fax, caller ID and voice/fax/data steering.

The IA3211 and IA3212 chipset is also known under the Siemens/Infineon DAA 2000 device part number.
