Portable audio player design aids
differentiation
A new reference design provides a complete hardware and software solution to help consumer electronics OEMs differentiate their portable digital audio products in an intensely competitive market.
A new ready-to-use reference design provides a complete hardware and software solution with a low bill of materials (BOM), low power consumption and turnkey support for features that can help consumer electronics OEMs differentiate their portable digital audio products in an intensely competitive market Based on TI's digital audio family of digital signal processors (DSP), the production-ready system minimises design complexity and manufacturing costs, enabling the quick development of competitively priced digital audio players

Data buffer has dual multiplexer
Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
Products based on the design can operate for up to 45h on a single AA or up to 20h on a single AAA battery.
The low-power, high performance DSP can handle all of the processing required for a portable audio player with overhead remaining to allow manufacturers to differentiate their products by adding additional features, such as TI's proprietary Time Scale Modification (TSM) software or 3rd party post-processing algorithms.
"The portable audio reference design is one more example of the investment that TI is making for our customers, providing the tools they need to succeed in a competitive market", said Chris Schairbaum, Worldwide Business Manager of TI's Portable Audio and Infotainment business unit.

Texas Instruments has unveiled the latest pair of programmable DSPs in its ultra-power-efficient TMS320C55x family of digital signal processors.
"Portable digital audio player manufacturers can turn to TI for flexible turnkey solutions that they can utilise to get to market quickly with feature-rich products".
The new reference design offers broad support for a variety of features and functionality, including: all major audio compression-decompression algorithms, including mp3, Windows Media Audio (WMA), Advanced Audio Coding (AAC), mp3Pro and voice recording, as well as a built-in FM receiver; high-quality timescale modification (TSM) algorithm, enabling the playback of recorded sound with normal pitch at up to twice the speed, or slowing playback down to half the speed; the commonly used MultiMedia Card (MMC) removable Flash card, and can be modified to support other Flash formats, as well as hard disk drives; USB 2.0 support, enabling easy connection to computers; a flexible DSP solution, allowing OEMs to add post-processing or converge other types of functionality, such as voice recording, into portable digital audio players; and extensive multilanguage support, based on TI's industry-leading eXpressDSP software technology, simplifying development while providing flexibility for system extension.
TI's portable audio player reference design and complete manufacturing kit are available today.
Manufacturers can also plan to design their next-generation hard disk drive-based portable audio players on a new feature-enhanced reference design from TI, which is expected to be available in the third quarter of this year.
