IC, LA9241M
Pin No.Pin NameI/ODescription
Pin to which external pickup photo diode is connected. RF signal is created by adding
1FIN2Iwith the FIN1 pin signal. FE signal is created by subtracting from the FIN1 pin signal.
2FIN1IPin to which external pickup photo diode is connected.
Pin to which external pickup photo diode is connected. TE signal is created by
3EIsubtracting from the F pin signal.
4FIPin to which external pickup photo diode is connected.
5TBIDC component of the TE signal is input.
6TE�IPin to which external resistor setting the TE signal gain is connected between the TE pin.
7TEOTE signal output pin.
8TESIITES OTrack Error Sense� comparator input pin. TE signal is passed through a band-
pass filter then input.
