The SAA7128AH; SAA7129AH expects digital Y, C
and C
“ITU-R BT.601” .
For C and CVBS outputs, deviating amplitudes of the
colour difference signals can be compensated by
independent gain control setting, while gain for luminance
is set to predefined values, distinguishable for 7.5 IRE
set-up or without set-up.
