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).

FEATURES
• Extended operating ambient temperature range of −40 to +85°C
• Integrated bitstream DAC with differential outputs, operating at 96fswith 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 fsmode
• 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.
