Advanced ADPCM SOUND DSP for Mobile QS6400 www.DataSheet4U.com 1. General Description . QS6400 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).
