1. CIRCUIT DESCRIPTIONS

Recently, most CD LSI's have included DAC, RF amplifier and other peripheral circuits, as well as the core circuit DSP.

This series of mechanisms employ a multi-task LSI UPD63763GJ, which has CD-ROM decoder and MP3/WMA decoder

in addition to the CD block as shown in the Fig.1.0.1. This enables to reproduce a CD-ROM where MP3/WMA data is

recorded.
