RF AGC input of playback Y level.
The playback video signal output
from Pin 14 (MTOUT) passes
through an external ATF TRAP,
AFM TRAP, and C TRAP, and is
then input to Pin 10 (RFAGCIN)
again.
DC is cut off by internal capacitor.
When not used, connect this pin to
Vcc.
Determines the dropout detection
level.
