Preliminary specification
DSP for CD and DVD-ROM systems
SAA7335
APPLICATION INFORMATION
The complete data path chipset consists of two ICs, the CD decoder (or DSP) device and the block decoder/host
interface manager. In addition to these components a general purpose microcontroller and tracking servo is necessary
to produce a complete controller system for a DVD mechanism. The DSP, block decoder and microcontroller are shown
highlighted in Fig.21. An ADC application circuit is illustrated in Fig.22.
