SC9642
CAR-CD DIGITAL SERVO SIGNAL PROCESSOR(SLAVE MODE)
DESCRIPTION
The SC9642 is a single-chip CD processor for digital servo and ASIC
circuit. This LSI incorporates CD servo controller, CD signal processor,
digital audio DAC and built-in CPU interface.
FEATURES
* Supports 1X to 2X speed playback
* Command and sub code transmission adopts tri-line communication
or parallel communication.
* Built-in MCU controls the CD and state feedback by communication
instructions of the communication bus.
* Supports format of CD-A/V, CD-R, CD-R/W and CD-ROM
APPLICATIONS
* CD, VCD and MP3 player
* Desk audio system
LQFP-64-10x10-0.5

Crystal oscillation circuit input. When the master clock is input externally, input it
from this pin.
Crystal oscillation circuit output.
Connect ground.
Control the spindle motor (during focusing and jumping, if MOT_CTRL output high
level signal, it can control the MOT control port of SA9529 after through 3 voltage
drop diodes, then prevent the spindle reverse; in other condition, the MOT-CTRL
output low level).
