Y and composite video signal output for
the viewfinder. A composite video
signal is output when Pin 28 (Y/VSEL)
is high.
Control input for white level insertion of
the Y and composite video signals for
the viewfinder (output from Pin 19).
The chroma signal for the viewfinder
output from Pin 21 (EVFCOUT) is also
muted simultaneously. This pin takes
precedence over the Pin 22 (VOB1)
control signal.
Low (0 to 0.8 V) : normal operation
High (2 V to V
Chroma signal output for the
viewfinder. When Pin 28 is high, the
output amplifier goes into power saving
mode and Pin 21 goes to high
impedance.
Control input for black level insertion of
the Y and composite video signals for
the viewfinder. The chroma signal for
the viewfinder is also muted.
