(Point 1) When suspected SYNC input to NJW1301, necessary on 5H(1H:horizontal term ,about 63.5us) of
pulth width of suspected SYNC.
(Point 2) Investigation Crosstalk level when design for depend to application.
(Point 3) Do not input the intermediate step signal at External terminal to use OSD signal for EXTRGB.
The EXRRGB accept only white(0.7V,white 100%) – black(0V)signal.
