GENERAL DESCRIPTION
The SAA7348 All Compact Disc Engine (ACE) combines the functionality of a CD decoder (LO9585), a digital servo (OQ8868) and a microcontroller core (80C51 based) on a single chip. It was developed for high speed CD-ROM applications but, due to the large scale integration, can also be used in other CD applications. The internal microcontroller makes it possible to develop other applications quickly. The microcontroller can operate with internal or external ROM.
FEATURES
• Focus servo loop
• Radial servo loop
• Built-in access procedure with fast track count possibilities
• Sledge motor servo loop with pulsed sledge support
• High speed error correction, up to sixteen times over-speed
• Supports three different over-speed ranges with only one external crystal
• Lock-to-disc mode
• Full turntable motor control
• Full error correction strategy, t = 2 and e = 4
• All standard decoder functions implemented digitally
• Adaptive digital HF equalizer
• FIFO overflow concealment for rotational shock resistance
• Digital audio interface (EBU), audio and data
• 2 and 4 times oversampling integrated digital filter, including fs mode
• Audio data peak level detection
• Kill interface for DAC deactivation during digital silence
• All TDA1301 (DSIC2) digital servo functions
• Low focus noise
• Improved playability on ABEX TCD-721R, TCD-725 and TCD-714 discs
• Automatic closed loop gain control available for focus and radial loops
• On chip clock multiplier allows the use of 8.4672 MHz crystal
• S2B serial interface with host controller
• Double speed servo
• Integrated engine controller (high speed embedded 80C51)
• External program support.
