Output terminal of RF summing amplifier. Checkpoint of Eye pattern.

Anti-reverse input terminal for RF summing amplifier.

The gain of RF amplifier is decided by the connection resistance between RF_M and

RFO terminals.

This is a pin where the selection time constant is externally connected to control the

RF level. (Pull down)

APC amplifier output terminal.

APC amplifier input terminal.

RFI-V amplifier inverted input pin.

These pins are connected to the A+C and B+C pins of the optical pickup, receiving by

currents input.

Bias adjustment pin of the focus error amplifier. (Not connected)

F and EIV amplifier inverted input pins.

These pins are connected to the F and E of the optical pickup, receiving by current

input.

Gain adjustment pin of the I-V amplifier E. (When not in use of BAL automatic

adjustment)

GND connection pin.

Output terminal for tacking-error amplifier. Output E-F signal.

BAL adjustment comparator input pin. (Input through LPF from TEO)

Input terminal for tracking error.

Window-comparator input terminal for detecting ATSC. (Pull up)

Input terminal for tracking-zero cross comparator.

Capacitor connection pin for the time constant used when there is defect. (Pull up)

Output terminal for DC voltage reduced to half of VCC+VEE.

Input terminal for focus-zero cross comparator.
