Integration Associates Introduces Analog Front End for V92/56K Modems; 16-bit Codec Sets New Standard at 91dB Dynamic Range Performance.MOUNTAIN VIEW, Calif. -- Integration Associates, a fabless semiconductor company A fabless semiconductor company specializes in the design and sale of hardware devices implemented on semiconductor chips. It achieves an advantage by outsourcing the fabrication of the devices to a specialized semiconductor manufacturer called a semiconductor foundry or "fab. offering analog and mixed-signal semiconductor solutions for wireless and wireline communications, today announced the launch of the IA3120 and IA3121 modem analog front ends (MAFE MAFE Maintenance of Air/FMF Expeditionary Equipment ). These products are specifically designed for software modem architectures (soft modems) up to V.92/56K in a variety of embedded applications such as set-top boxes and point-of-sales (POS (1) See point of sale and packet over SONET. (2) "Parent over shoulder." See digispeak. POS - point of sale ) terminals, where the modulation function is performed by the main processor. Additional features such as the on-chip hybrid, caller ID, line-in-use, 911, and ring detection allow for small and effective discrete DAA DAA - Distributed Application Architecture: under design by Hewlett-Packard and Sun. A distributed object management environment that will allow applications to be developed independent of operating system, network or windowing system. implementations to address worldwide markets. Jean-Luc Nauleau, chief executive officer for Integration Associates, commented, "The IA3120 and IA3121 have been developed to raise the standard in the industry for low-speed and high-speed soft modems, leveraging our long-time commitment to telephony applications. These products provide application designers with all of the features they need within a compact package, while offering innovative solutions to further reduce the overall modem function cost. They also speed up and simplify the design-in process." The IA3120/21 is a cost effective and value added solution addressing today's need for high performance modems, while achieving further reductions in space, power and cost. By incorporating typical external DAA functions such as the ring detection, line matching hybrid, line-in-use, and parallel pick-up detection, the IA3120/21 reduces the bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. (BOM), such as the ring detection optoisolator, and preserves valuable PCB PCB: see polychlorinated biphenyl.

Controlled through a simple and popular standard MAFE interface, this feature-rich device eases the overall design in of a modem function. Technical Specifications The IA3120/21 operate from a single +3.3V supply while still offering transmit and receive capability of up to +1dBm into a 600 ohm resistive network. Built around a high performance 16-bit codec, the IA3120/21 provide up to 91dB dynamic range and 88dB SNR See signal-to-noise ratio. SNR - signal-to-noise ratio adequate for all modem speeds. The IA3120/21 eliminate the need for a dedicated crystal oscillator by supporting a 27Mhz clock input typically found in set-top box applications. Ideal for DSP- or RISC-based soft modem applications, the IA3120/21 feature programmable sampling rates, power conservation modes, and differential hybrid circuitry to directly connect to a line-matching transformer. On-chip ring detection circuitry eliminates the need for an external opto-coupler and can be configured for CTR-21, FCC (1) (Federal Communications Commission, Washington, DC, www.fcc.gov) The U.S. government agency that regulates interstate and international communications including wire, cable, radio, TV and satellite. The FCC was created under the U.S. , and other worldwide telephone standards. Availability/Pricing The IA3120 is available in a 20-pin QSOP QSOP Quarter Size Outline Package QSOP Quarter Small Outline Package QSOP Quad Small Outline Package QSOP Quadripartite Standing Operating Procedures QSOP Quarterly Standing Order Plan QSOP Quality Standard Operating Procedure QSOP Quarter Sized Outline Package package, and is priced at $3.60 for quantities of 1,000. An evaluation board is available for the IA3120 with a FCC68 compliant line interface at a price of $50. The IA3121 is available in a 28-pin QSOP package, and is priced at $4.40 for quantities of 1,000.
