Variable de-emphasis
integrating pin.
(Connect a 2700pF capacitor
and a 3.3k 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 3k 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.)
Variable de-emphasis output
pin.
(Connect a 4.7µF non-polar
capacitor between Pins 29
and 30.)
