YMU769

( DataSheet : www.DataSheet4U.com ) YMU769 MA-5S Mobile Audio 5 Type S „ Outline ry a y n iar m n i i l rle im P e Pr YMU769 has a virtual speaker image function, so that it is the most suitable LSI as a sound source output device which is used in mobile phones for high functional game sounds or high quality ringing melodies, and so on. Synthesizer section in YMU769 adopts “stereophonic hybrid synthesizer system” that is given advantages of both FM synthesizers and Wave Table synthesizers, makes it possible to generate up to 32 FM voices and 32 Wave Table voices simultaneously. Since FM synthesizer is able to provide countless voices by specifying parameters with only several tens of bytes, memory capacity and communication band can be saved, and thus, the device exhibits the features in operating environment of mobile phones such as allowing distribution of arbitrary melodies with voices. On the other hand, Wave Table synthesizer can pronounce the voice stored in ROM, and in addition it can handle arbitrary ADPCM/PCM voices by sequencer. Furthermore, the Stream Playback function, and the time-variant low pass filter function by AL (Analog Lite) Synthesizer are equipped. YMU769 has two-channel virtual speaker image functions based on DVX technology, so that natural stereo sounds can be realized even in an environment such as two adjacent speakers on a small body like mobile phones. Integrated stereo speaker amplifiers make external components unnecessary and consequently i...
