| Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw MP3/WMA Decoder and MP3 Encoder IC PT8405 DESCRIPTION The PT8405 is a single chip MPEG audio encoder/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 PT8405 support is the Window Media Audio or WMA by Microsoft. With external AD converter interface or build-in S/PDIF interface, it can also compress incoming digital signal into MPEG1/2 layer 3 format, so called MP3. 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. * Support MPEG layer 3 all sampling frequency for encoding. * Time-stretch and pitch-shift functions for various applications, including language learning * Serial/parallel bit stream input interface * Parallel bit stream output interface * Build-in S/PDIF for MP3 encoding input * 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 1 fs: sampling frequency.
