Notes on Operation
1. Connection of the power supply pin
2. FSET pin
The FSET pin determines the cut-off frequency fc for the focus and tracking high-frequency phase compensation.
3. ISET pin
ISET current = 1.27V/R
= Focus search current
= Tracking jump current
= 1/2 sled kick current
4. The tracking amplifier input is clamped at 1V
BE
to prevent overinput.
5. FE (focus error) and TE (tracking error) gain changing method
(1) High gain: Resistance between FE pins (Pins 5 and 6) 100k
→
Large
Resistance between TA pins (Pins 11 and 12) 100k
→
Large
(2) Low gain: A signal, whose resistance is divided, is input to FE and TE.
6. Input voltage of microcomputer interface Pins 20 to 25, should be set as follows.

7. Focus OK circuit
(1) Refer to the "Description of Operation" for the time constant setting of the focus OK amplifier LPF and the
mirror amplifier HPF.
