Luminance trap filter connection pin. Connecting a trap filter eliminates the chrominance
band component included in the luminance signal, and reduces the amount of chrominance
color. Output impedance is approximately 2k
. This is effective only for composite video
output.
This pin is not connected within the IC.
This pin is not connected within the IC.
Video output method selector pin. NTSC when HIGH, PAL when LOW
Composite SYNC input. For LOW input, SYNC is output to YOUT and VOUT. At the same
time, DC clamping of the RGB signal takes place.
Color subcarrier input. Sine waves of a frequency corresponding to the required output method,
or pulse waves with a duty of 50%, should be input in a range not exceeding V
CC
-GND.
