VLSISolution yVS1033cVS1033C8. FUNCTIONAL DESCRIPTION8 Functional Description8.1 Main FeaturesVS1033 is based on a proprietary digital signal processor, VS DSP. It contains all the code and datamemory needed for MP3, AAC, WMA and WAV PCM + ADPCM audio decoding, MIDI synthesizer,together with serial interfaces, a multirate stereo audio DAC and analog output amplifiers and filters.Also ADPCM audio encoding is supported using a microphone amplifier and A/D converter. A UARTis provided for debugging purposes.8.2 Supported Audio CodecsMarkConventionsDescription+ Format is supported- Format exists but is not supportedFormat doesn’t exist8.2.1 Supported MP3 (MPEG layer III) FormatsMPEG 1.0 1 :Samplerate / HzMPEG 2.0 1 :Samplerate / HzMPEG 2.5 1 :Samplerate / HzBitrate / kbit/s32 40 48 56 64 80 96 112 128 160 192 224 256 32048000 + + + + + + + + + + + + + +44100 + + + + + + + + + + + + + +32000 + + + + + + + + + + + + + +Bitrate / kbit/s8 16 24 32 40 48 56 64 80 96 112 128 144 16024000 + + + + + + + + + + + + + +22050 + + + + + + + + + + + + + +16000 + + + + + + + + + + + + + +Bitrate / kbit/s8 16 24 32 40 48 56 64 80 96 112 128 144 16012000 + + + + + + + + + + + + + +11025 + + + + + + + + + + + + + +8000 + + + + + + + + + + + + + +1 Also all variable bitrate (VBR) formats are supported.Version 1.00, 2008-02-01 25
