Connecting pin 7 to Vcc sets the board to the NTSC mode, and connecting pin 7 to GND sets the board to the PAL mode. On the evaluation board, make connection by the jumper wire for the desired mode. Notes on Use When you connect C VIDEO OUT to TV and input characters from personal computer for example, you may notice rainbow-hued blurs along edges of characters displayed on the screen, or unevenness of color distribution. This phenomenon esults from mixing of Y-signal's high-frequency components into chrominance components (cross-color Interference), and does not represent a faulty operation of the board, -183-
