COMPONENTS DESCRIPTION
Drive for LCD unit
Receiving for the remote control unit
key scan start at base gose "L".
Generation of RF signal based on the signals from the APC circuit and pickup, and generation
of servo error (focusing error and tracking error) signals. Detection of dropout, anti-shock,
track crossing and off-track conditions, included gain control function during CD-RW.
Focusing, tracking, sled and spindle servo processing. Automatic adjustment (focusing,
tracking, gain, offset and balance) operations. Digital signal processing (DSP, PLL, sub-codes,
CIRC error correction, audio data Interpol ration) operations, and Microcomputer function.
Focusing coil, tracking coil, spindle motor and sled motor driver, disc loading and eject operation.
For SW3.3V AVR
