Integration Associates Announces Silicon EZDAA with Serial Codec
Integration Associates, a pioneering provider of telephony solutions, announced availability of its IA3131/ IA3222, the codec complement to its highly successful EZDAA portfolio. The new product is ideal for the continuing durable market for embedded modems and emerging VoIP markets.
The chipset has been designed to target soft modem applications such as alarm systems, stand-alone fax machines, Multi-Function Printers, Set-Top-Box and Point-Of-Sale terminals. Traditionally, such applications had been based in hardware modem solutions. Today's system requirements include the combination of voice and data communications with an increased flexibility to support different software drivers. The IA3131/IA3222 chipset allows for such flexibility providing an all function support for software modem and voice communications while at the same time reducing the total cost. The product achieves over 30% cost reduction in BOM compared to competitor solutions.
This chipset keeps the rich set of features supported in previous EZDAA family chipsets such as Caller ID, DTMF, continuous line-in-use monitoring, line voltage and loop-current monitoring, line reversal detection for both on- and off-hook and programmable ring detection threshold. The chipset, in addition has a serial 4-wire digital interface fully compatible with those commonly supported by ST processors, providing an easy path to transition from hard modem to a soft modem solution in the alarm, STB, POS, Fax and MFP markets. The interface also supports a set of Master/Slave modes allowing for any CPU or DSP to communicate with the chipset. The integrated clock input and PLL allows the device to operate without an external crystal when some specific modes are selected while also supporting the typical 27MHz clock of STB applications.
The IA3222 and IA3131 chipset implements Integration's successful and patented IsoBridge isolation technique, which eliminates the need for the typical and more expensive telecom isolation components, such as discrete capacitors, transformers, and optocouplers. Integration's IsoBridge technology can provide virtually unlimited high voltage isolation. The IsoBridge technology also has an inherent high immunity to RF disturbances. This further reduces BOM costs by eliminating the additional filtering components often found in competitor's solutions.
"The new chipset brings to market the most integrated and full-featured DAA solution for embedded applications," stated Jean-Luc Nauleau, Integration's CEO. Adding that the part now provides customers a choice of solution for both analog and digital DAA applications.
The IA3222 and IA3131 chipset is available 10-pin MSOP and 20-pin QSOP packages respectively. For high volume applications, the chipset allows to provide a DAA with worldwide programmability for a total BOM cost under $2.00. Evaluation boards and samples are available now and volume production will begin in first quarter of 2008.
