Pin to which external pickup photo diode is connected. RF signal is created by adding with the
FIN1 pin signal. FE signal is created by subtracting from the FIN1 pin signal.
Pin to which external pickup photo diode is connected.
Pin to which external pickup photo diode is connected. TE signal is created by subtracting from
the F pin signal.
Pin to which external pickup photo diode is connected.
DC component of the TE signal is input.
Pin to which external resistor setting the TE signal gain is connected between the TE pin.
TE signal output pin.
TES “Track Error Sense” comparator input pin. TE signal is passed through a band-pass filter
then input.

Pin to which external focusing phase compensation constants are connected between the FD and
FA pins.
Pin to which external focusing phase compensation constants are connected between the FD–
and FA– pins.
Pin to which external focusing phase compensation constants are connected between the FA and
FE pins.
FE signal output pin.
Pin to which external FE signal gain setting resistor is connected between the FE pin.
Analog signal GND.
Signal ended output of the CV+and CV- pin input signal.
Spndle amp input.
