Pin function
FG comparator inverted input pin.
No internal bias is applied.
FG comparator non-inverted
input pin. No internal bias is
applied.
FG comparator output pin.
Internal load impedance is 20 k
.
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.
Pin for connecting triangular
wave oscillator capacitor. Serves
for forced startup waveform
generation.
