2 GENERAL DESCRIPTION
The SAA7374 (CD7LV) is a low-voltage chip which
combines 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.
