SAA7326 Features
Extended operating ambient temperature range of -40 to +85 Cel
Integrated bitstream DAC with differential outputs, operating at 96fswith 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
Up to 2 times speed mode
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 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
Same playability performance as SAA737x (CD7)
Automatic closed-loop gain control available for focus and radial loops
Pulsed sledge support
Electronic damping of fast radial actuator during long jump
