Variable de-emphasis
integrating pin.
(Connect a 2700pF capacitor
and a 3.3kΩ resistor in series
between this pin and GND.)
Weight the variable
de-emphasis control effective
value detection circuit.
(Connect a 0.047µF capacitor
and a 3kΩ resistor in series
between this pin and GND.)
Determine the restoration
time constant of the variable
de-emphasis control effective
value detection circuit.
(The specified restoration
time constant can be obtained
by connecting a 3.3µF
capacitor between this pin
and GND.)
