| Tel: 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw MP3 Audio Decoder IC PT8402B DESCRIPTION The PT8402B 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. In additional to decoding function, this chip also include a high-performance D/A converter and headphone driver, so user can eliminate the need of external DAC and output circuit. With external A/D converter, it can also compress incoming signal by using ADPCM algorithm, therefore it can also playback ADPCM bitstream. FEATURES Support all the sampling frequency of MPEG1 (32/44.1/48KHz), MPEG2(16/22.05/24KHz) and MPEG2.5(12/11.025/8KHz). Parallel/Serial bit stream input interface I2S/Normal audio data output format delivered via an serial bus Power save mode support DAC master clock (256*fs / 384*fs for 16 / 24 bit DAC) is supported Build-in DAC and headphone amp. Build-in Volume and Digital Equalizer Control Aux input for additional analog music source through AUXR and AUXL ports Bass Booster, 3D Sound. Low Operating Voltage, 2.5V. Available in 100 pins and 80 pins, TQFP and LQFP Package APPLICATIONS Portable MP3 player PDA CD/MP3 player All other MP3 applications.
