GENERAL DESCRIPTION

The SAA7324 (CD10 II) is a single chip combining the functions of a CD decoder, digital servo and bitstream DAC. 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

• 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 4 times speed mode

• Low voltage operation at up to 2 times speed

• 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

• Two and four 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.
