23
I
DVD APC input.
24
I
CD APC input.
25
G
Servo block ground.
26
I
APC On/Off control. A high level activates LD output. (open is low)
27
O
Mirror detect output.
I
Mirror top and bott
30
I
Mirror low-pass filter pins. Connected to VPB pin 19 via a capacitor.
31
I
RF input signal for mirror. AC coupled inputs for the mirror detection circuit from
MEVO pin 32.
RFDC bottom envelope out. Pull-In or bottom clamped RF envelope signal output
32
O
for mirror detection.
Linking Signal In/Mirror Monitor Out. In the linking area, the mirror and tracking
33
I,O
error outputs are disabled when this pin goes high. When the monitor output signal
is selected by the Control H register, mirror-related signals can be observed.
Defect output. When the Pull-In signal level is below the detection level, or when
34
O
the RF signal level is below the detection level, the DFT output goes high. The
defect output is selected by the serial port.
35
I
Pull-In top hold. Connected to VPB pin 19 via a capacitor.
36
O
1.25V servo block reference voltage output.
