SAA7325数据手册恩XP中文资料规格书

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)
