Pin function

VCC1 FG comparator inverted input pin.

No internal bias is applied.

FG comparator non-inverted

input pin. No internal bias is

36

applied.

FG comparator output pin.

Internal load impedance is 20 kΩ.

VCC1

Capstan motor forward/reverse

select pin. The voltage at this pin

(with hysteresis) selects forward

or reverse rotation.

This pin selects bias supply to

capstan circuits other than FG

comparator. Setting the pin to

Low cuts off the bias supply.

Capstan motor standby pin.

FG amplifier output pin.
