Pin Name I/O
Pin to which external pickup photo diode is connected. RF signal is created by adding
FIN2 I
with the FIN1 pin signal. FE signal is created by subtracting from the FIN1 pin signal.
FIN1 I Pin to which external pickup photo diode is connected.
Pin to which external pickup photo diode is connected. TE signal is created by
E I
subtracting from the F pin signal.
F I Pin to which external pickup photo diode is connected.
TB I DC component of the TE signal is input.
TE– I Pin to which external resistor setting the TE signal gain is connected between the TE pin.
TE O TE signal output pin.
TES "Track Error Sense" comparator input pin. TE signal is passed through a band-
TESI I
pass filter then input.
SCI I Shock detection signal input pin.
TH I Tracking gain time constant setting pin.
TA O TA amplifier output pin.
Pin to which external tracking phase compensation constants are connected between
TD– I
the TD and VR pins.
TD I Tracking phase compensation setting pin.
JP I Tracking jump signal (kick pulse) amplitude setting pin.
TO O Tracking control signal output pin.
FD O Focusing control signal output pin.
Pin to which external focusing phase compensation constants are connected between
FD– I
the FD and FA pins.
Pin to which external focusing phase compensation constants are connected between
FA I
the FD– and FA– pins.
Pin to which external focusing phase compensation constants are connected between
FA– I
the FA and FE pins.
FE O FE signal output pin.
FE– I Pin to which external FE signal gain setting resistor is connected between the FE pin.
AGND — Analog signal GND.
SP — Single ended output of the CV+ and CV– pin input signal.
SPI I Spindle amp input.
SPG I Pin to which external spindle gain setting resistor in 12 cm mode is connected.
Pin to which external spindle phase compensation constants are connected together
SP– I
with SPD pin.
SPD O Spindle control signal output pin.
SLEQ I Pin to which external sled phase compensation constants are connected.
SLD O Sled control signal output pin.
SL–, SL+ I Sled advance signal input pin from microprocessor.
JP–, JP+ I Tracking jump signal input pin from DSP.
