GENERAL DESCRIPTION

The SAA7325 (CD10) 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

FEATURES

• Single speed operation

• 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

• 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)
