MP3/WMA Decoder IC

PT8406

DESCRIPTION

The PT8406 is a single chip MPEG audio decoder capable of decoding all layers compressed

elementary streams, as specified in MPEG 1 and MPEG 2 ISO standards, including the so called MP3.

Enhance with time-stretch and pitch-shift functions, this chip is suitable for language learning

application. Another decoding function that PT8406 support is the Window Media Audio or WMA by

Microsoft.

FEATURES

• Decoder supports all layer and all the sampling frequency of MPEG1 (32/44.1/48KHz), MPEG2

(16/22.05/24KHz) and MPEG 2.5.

• Support Microsoft Window Media Audio V2/V7/V8/V9 format for decoding.

• Time-stretch and pitch-shift functions for various applications, including language learning

• Serial/parallel bit stream input interface

• Parallel bit stream output interface

• DAC master clock (256*fs¹/ 384*fs for 16 / 24 bit DAC) is supported

• Spectrum analyzer output register for spectrum graphic display

• Build-in volume and digital equalizer control

• Low operating voltage, 2.5V.

• 44-pin Plastic LQFP

APPLICATIONS

• Portable MP3/WMA player

• Language learning machine

• PDA, Electronic dictionary

• All other MP3/WMA applications
