Chip set delivers CD-quality audio to entry-level handsets

Agere Systems introduced the TrueNTRY X125 platform that delivers multimedia features to entry-level mobile handsets. The platform consists of a chip set, software, and a development kit. Agere claims that such handsets should carry a bill of materials (BOM) as low as $30. This higher speed benefit of the X125 platform makes downloading CD-quality music faster and easier.

Features that help reduce the BOM include an integrated speaker amplifier; integrated CD quality stereo; a polyphonic sound synthesizer; a USB 2.0 On-the-Go controller (with charging capabilities); and power-management and battery-charging circuits.

The X125 platform supports advanced audio processing including dynamic noise suppression, echo cancellation, full-duplex speakerphone, and a stereo equalizer. The analog baseband integrates the GSM/GPRS/EDGE features such as power control, frequency control, analog baseband processing, audio mixing and conversion, real-time clock, and power management.

Production quantities will ship next month. For more information, visit www.agere.com.
