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. Features § § § § § § § § § § Supports all the Sampling Frequency of MPEG1 (32/44.1/48KHz) and MPEG2(16/22.05/24KHz). Supports AAC ADTS, ADIF Bitstream. Serial Bit Stream Input Interface I2S/Normal Audio Data Output Format delivered via a Serial Bus Power Saving Mode Support DAC Master Clock (256*fs / 384*fs for 16 / 24 bit DAC) is supported Built-in Volume and Digital Equalizer Control Bass Booster, 3D Sound. Low Operating Voltage, 2.5V. 100-pin, LQFP Package Applications § § § § Portable MP3 Player PDA CD/MP3 player All other MP3 applications.
