IC, LA9241 M
Pin No.
Pin Name J/o
Description
1
Pinto which external pickup photo diode is connected. RFsignal iscreated by adding
FIN2
I
with the FIN 1 pin signal. FE signal is created by subtracting from the FIN 1 pin signal.
2
FIN1
I
Pin to which external pickup photo diode is connected.
3
Pin to which external pickup photo diode is connected. TE signal is created by
E I
subtracting from the F pin signal.
4
F
I Pin to which external pickup photo diode is connected.
5 TB I
DC component of the TE signal is input.
6 TE- 1 Pin to which external resistor setting the TE signal gain is connected between the TE pin.
7 TE o TE signal output pin.
8
TES “Track Error Sense” comparator input pin. TE signal is passed through a band-
TESI
1
pass filter then input.
9 SCI
I
Shock detection signal input pin.
10
TH I Tracking gain time constant setting pin.
11
TA o TA amplifier output pin.
12
Pin to which external tracking phase compensation constants are connected between
TD– 1
the TD and VR pins.
13 TD I Tracking phase compensation setting pin.
14 JP
I
Tracking jump signal (kick pulse) amplitude setting pin.
15
TO o Tracking control signal output pin.
16 FD o Focusing control signal output pin.
17
Pin to which external focusing phase compensation constants are connected between
FD– 1
the FD and FA pins.
18
Pin to which external focusing phase compensation constants are connected between
FA I
the FD– and FA– pins.
19
Pin to which external focusing phase compensation constants are connected between
FA-
1
the FA and FE pins.
20
FE o FE signal output pin.
21 FE-
1 Pin to which external FE signal gain setting resistor is connected between the FE pin.
22 AGND Analog signal GND.
23 NC
No connection.
24 SP o Single ended output of the CV+ and CV– pin input signal.
25
SPG
I
Pin to which external spindle gain setting resistor in 12 cm mode is connected.
26
Pin to which external spindle phase compensation constants are connected together
sP–
1
with SPD pin.
2’7
SPD
o Spindle control signal output pin.
28
SLEQ
I Pin to which external sled phase compensation constants are connected.
29
SLD
o
Sled control signal output pin.
30,31 SL–, SL+
I
Sled advance signal input pin from microprocessor.
32,33
JP–, JP+
I Tracking jump signal input pin from
DSP.
34
TGL
I
Tracking gain control signal input from DSP. Low gain when TGL = H.
35 TOFF
I
