SAA7327数据手册恩XP中文资料规格书

描述 Description

GENERAL DESCRIPTION
The SAA7327 (CD7 II) is a single chip combining the functions of a CD decoder, digital servo and bitstream DAC, especially designed for Video CD applications. 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
• Integrated bitstream DAC with differential outputs, operating at 96fswith 3rd order noise shaper; typical performance of−95 dB signal-to-noise ratio (EIAJA-weighted)
• Separate serial input and output interfaces allow data ‘loopback’ mode for use of onboard DAC as stand-alone DAC for digital audio signals
• Up to 2 times speed mode
• Lock-to-disc mode
• Full error correction strategy, t = 2 and e = 4
• Full subcode (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
• Improved playability performance
