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.
