描述 Description

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’ registersFEATURES
? 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)
