Pin 19 (AFT OUT)
Since an AFT output is provided by a high impedance
source, the detection sensitivity can be set by an external
resistor.
The muting operation will be on in following two cases;
1) the APC is out of locking,
2) the video output becomes small enough in a weak
electric field.

note: In the case of 5 V supply, it should be considered that the maximum AFT and RF AGC output are
less than 4.2 V and 4.7 V, respectively.
Pin 20 (EQ F/B)
Both the external coil and capacitor determine the frequency
response of EQ output.
The series connected resistor is for damping.
