NC
Inputs the SIF signal from the first SIF output.
Set the input level to 90dBµV or lower because of
the dynamic range of the internal filter.
This is the FM feedback filter pin. It is composed
of a C and R filters.
1µF is normally used as the capacitance.
If the capacitance is a low value, the audio output
level is small at low frequencies.
Moreover, the audio output level can be made
smaller by increasing the resistance connected in
series.
Use a resistance of 3kΩ or higher.
This is the first SIF output.
In case of inter carrier, the chroma carrier is bigger
than split carrier applications, so that it is
recommended to connect a filter externally.
