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)
