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
z Support all the sampling frequency of MPEG1 (32/44.1/48KHz), MPEG2(16/22.05/24KHz) and MPEG2.5(12/11.025/8KHz). z Parallel/Serial bit stream input interface z I2S/Normal audio data output format delivered via an serial bus z Power save mode support z DAC master clock (256*fs / 384*fs for 16 / 24 bit DAC) is supported z Build-in DAC and headphone amp. z Build-in Volume and Digital Equalizer Control z Aux input for additional analog music source through AUXR and AUXL ports z Bass Booster, 3D Sound. z Low Operating Voltage, 2.5V. z Available in 100 pins and 80 pins, TQFP and LQFP Package
APPLICATIONS
z All other MP3 applications.
