TI Introduces New Reference Design for Portable Digital Audio Players
June 8, 2004 (HONG KONG) -- Texas Instruments (TI) announced the availability of the latest advancement in a series of portable entertainment reference designs. The new ready-to-use 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 original equipment manufacturers (OEM) differentiate their portable digital audio products in an intensely competitive market.
Based on the digital audio family of digital signal processors (DSP), the production-ready system minimizes design complexity and manufacturing costs, enabling the quick development of digital audio players. Products based on the design can operate for up to 45 hours on a single AA or up to 20 hours on a single AAA battery. The 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 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.
The portable audio player reference design and complete manufacturing kit are available. Manufacturers can also plan to design their next-generation hard disk drive-based portable audio players on a new feature-enhanced reference design, which is expected to be available in the third quarter of this year.
