Datasheet
Optical Silicon DAA
Modem/Lineside Chipset
DESCRIPTION
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.

... A ring detector is built into the IA3212, which can be configured as either a "full wave" detector or a "half wave" detector. In the full wave mode, a pulse is generated al the IA3211 "ring detect" output pin for each half cycle of the ring signal. In the half wave mode, one pulse is generated for each full cycle of the ring signal ...

... Audio Interface Transmit Audio Interface The IA3211 provides a single ended transmit interface. When used with a 120KΩ resistor in series, the IA3211 and IA3212 chipset presents an overall 0dB transmit path between the audio source on the host side and the phone line. In addition, the TXAMP input is biased internally to the ACREF voltage IA3211 & ...

... On-hook Operation On-hook Monitor – Caller ID Mode Asserting either the ONHKM input (or the inverse ONHKML input) on the IA3211 puts the DAA into SNOOP mode or on- hook monitor mode. This is used primarily for Caller ID purposes. When in SNOOP mode, the DAA draws a maximum of 500µ ...

... Then a trip point can then be set about 30% below that idle level. If the V/F function is not needed, the components connected to pin 19 of the IA3211 and IA3212 can be left out. Note that the V/F does not function when off-hook SNOOP mode. HZ 0805 B 601R ...

... Most telephone specifications require very high voltage isolation between the loop circuit and the user circuit as a safety issue. The IA3211 and IA3212 chipset design uses opto-isolators to achieve an IA3211 & IA3212 isolation barrier 2500 volts. This isolation can only be realized if the circuit board design and construction is also capable of withstanding this kind of high voltage ...

... RNG follows LSTAT. Line status – Line in use and parallel pick-up detection. In idle mode, LSTAT provides a V/F transfer function from the phone line voltage. In on-hook monitor and off-hook modes, LSTAT outputs a single pulse if the line current is suddenly decreased. IA3211 & IA3212 IA2312 7 ...
