5. RGB output circuit
The fast blanking pin has a second detection level at 3.5V
When this level is exceeded the RGB outputs are blanked so that
"on screen display"signals can be applied to the outputs
The output signal has an amplitude of approximately 4V,black to white,
with nominal control setting.
The nominal black level is 1.3V.
