Digital servo processor and Compact Disc
decoder with integrated DAC (CD10)
Product specification
SAA7326
1 FEATURES
• Extended operating ambient temperature range of
−40 to +85 °C
• Integrated bitstream DAC with differential outputs,
operating at 96fs with 3rd-order noise shaper; typical
performance of −90 dB signal-to-noise ratio
• Separate serial input and output interfaces allow data
‘loopback’ mode for use of onboard DAC with external
Electronic Shock Absorption (ESA) systems
• Up to 2 times speed mode
• Lock-to-disc mode
• Full error correction strategy, t = 2 and e = 4
• Full CD graphics interface
• All standard decoder functions implemented digitally on
chip
• 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 external DAC deactivation during digital
silence
• All SAA737x (CD7) digital servo and high-level functions
• Low focus noise
• Same playability performance as SAA737x (CD7)
• Automatic closed-loop gain control available for focus
and radial loops
• Pulsed sledge support
• Electronic damping of fast radial actuator during long
jump
• Microcontroller loading LOW
• High-level servo control option
• High-level mechanism monitor
• Communication may be via TDA1301/SAA7345
compatible bus or I2C-bus
• On-chip clock multiplier allows the use of 8.4672,
16.9344 or 33.8688 MHz crystals or ceramic
resonators.
2 GENERAL DESCRIPTION
The SAA7326 (CD10) is a single chip combining the
functions of a CD decoder, digital servo and bitstream
DAC. It has an extended operating ambient temperature
range when compared with other CD10 variants.
The decoder/servo part is based on the SAA737x (CD7)
and is software compatible with this design. Extra
functions are controlled by use of ‘shadow’ registers
(see Section 7.15.3).
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.
