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.
