UPD63763CGJ
Audio output
MP3/WMA
decoder
UPD63763CGJ, multifunctional LSI used in this device, has built-in CD-ROM decoder and MP3/WMA decoder, as shown
in Fig.1.0.1, as well as the conventional CD block, allowing to play CD-ROMs, in which MP3/WMA files are recorded,
while the recent mainstay of the CD LSI is the LSI integrating the core DSP with DAC or RF amplifier, which are generally
used as peripheral circuits.
