The SAA7372 is a single chip combining the functions of a CD decoder IC and digital servo IC. The decoder part is based on the SAA7345 (CD6) with an improved error correction strategy. The servo part is based on the TDA1301T (DSIC2) with improvements incorporated, extra features have also been added. 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.
