SAA7804
description
The SAA7804, is a single chip solution CD audio decoder, digital servo, audio DAC, pre-amp, laser driver and integrated ARM7TDMI-S microprocessor, targeted at a range of CD applications. The channel decoder design is derived from the SAA7817 DVD decoder IC, with optimization and design improvements specifically for CD audio (e.g. improved CD playability). The digital servo, analog pre-amp, laser driver and audio DAC blocks are improved designs based on the SAA7824 CD decoder IC. Further architectural enhancements to the design have been made to integrate system functionality and reduce the system cost of ownership. The SAA7804 IC supports a generic architecture that will form the basis of future variants in the SAA7804 IC family optimized for different CD applications.
