Preliminary Reference
PT8402
Description
The PT8402 is a single chip MPEG audio decoder capable of decoding all layers of compressed elementary
streams, as specified in MPEG 1 and MPEG 2 ISO standards, including the so-called MP3. Another decoding
function that PT8402 supports is AAC (Advance Audio Coding.).
In additional to decoding function, this chip also includes a high-performance D/A converter and headphone driver,
so the 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.
