Product Summary

The SAA7324H is a single chip combining the functions of a CD decoder, digital servo and bitstream DAC. The decoder/servo part is based on the SAA737x (CD7) and is software compatible with this design. Extra functions are controlled by use of shadow registers (see Section 7.15.3). Supply of this Compact Disc IC does not convey an implied license under any patent right to use this IC in any Compact Disc application.

Parametrics
