SAA7378GP

INTEGRATED CIRCUITS Data Sheet SAA7378GP Single Chip Digital Servo Processor and Compact Disc Decoder (CD7) Preliminary specification: Version 1.0 Philips Semiconductors May1995 Philips Semiconductors Preliminary specification: Version 1.0 Digital Servo Processor and Compact Disc Decoder (CD7) SAA7378GP 1. FEATURES Single speed mode. Full error correction strategy, t = 2 and e = 4. All standard decoder functions implemented digitally on chip. FIFO overflow concealment for rotational shock resistance. Digital audio interface (EBU), audio only. 2 - 4 times oversampling integrated digital filter. Audio data peak level detection. Kill interface for DAC deactivation during digital silence. All TDA1301 (DSIC2) digital servo functions, plus extra hi-level functions. Low focus noise. Communication via TDA1301/SAA7345 compatible bus. On chip clock multiplier allows the use of 8.4672MHz crystal. 2. GENERAL DESCRIPTION CD7 (SAA7378GP) is a single chip combining the functions of a CD decoder IC and Digital Servo IC. The decoder part is based on CD6 (SAA7345GP) with an improved error correction strategy; the servo part is based on DSIC2 (TDA1301T) with improvements incorporated. 3.
