Component Name
Application/Function
Operation/Condition/Compatibility
Generation of RF signal based on the sig-
nals 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 (focus-
ing, tracking, gain, offset and balance) oper-
ations. Digital signal processing (DSP, PLL,
sub-codes, CIRC error correction, audio
data interpolaration) operations, and
Microcomputer function.
Focusing, tracking, sled and spindle servo
processing. Automatic adjustment (focus-
ing, tracking, gain, offset and balance) oper-
ations. Digital signal processing (DSP, PLL,
sub-codes, CIRC error correction, audio
data interpolaration) operations, included
CD-text decoder and Microcomputer func-
tion.
Focusing coil, tracking coil, spindle motor
and sled motor driver, disc loading and
eject operation.
2nd low pass filter for audio signals
LD power control
When D.5V SW is turned on, Q2 and Q3
are turned on, and A.+8V is supplied to low
pass filter circuit and D/A converter.
When PON goes Hi, Q4 and Q5 are turned
on, and BU+5V is supplied to microproces-
sor peripheral circuit, IC1 and the pickup.
