Advanced ADPCM SOUND DSP for Mobile QS6400
www.DataSheet4U.com
1. General Description
Q. S6400 is a high quality sound DSP for mobile phones that plays music through a built-in
ADPCM decoder with sound font rom.
QS6400 is equipped with HWASS's QPCM synthesizer,which is capable of generating up to 64
voices with different tones.
QS6400 can also play two channels of wavefiles of differing sampling rates.
Since data in the FIFO buffer is processed on demand, the length of the data(MIDI & WAVE) is not
limited, making QS6400 an excellent platform for applications such as incoming melody
distribution service.
The MIDI handler built in to QS6400 can play MIDI data without an extra buffer.
Included is a PWM module for audio out with a maximum output of 500mw at 8Ω load
registance(PVDD=4.0V).
For earphone use, QS6400 provides a single-ended stereophonic output terminal.
To operate QS6400 to full capability, "Standard MIDI File(SMF) Format 0" is recommended.

9) D/A interface : This block generates 16bit DAC interfacing out for high qwuwawli.tDyatasSoheuent4Ud..com
If you have an additonal DAC, you can also use this interfacing out.
When you use the DAC OUT mode, earphone is disabled.
10) Sound font : This is an embedded maskrom for GM 128 sound map and 47 percussion.
The sound font built in this device stores the sampling data according to
GM 128 sound map. Additionally QS6400 has sampling data to support
korean traditional music.
