Application example (NTSC color TV signals)
External dimensions (Units: mm)
Operation notes
(1) Input impedance at the input terminals should be as
low as possible as the analog RGB signal is clamped
there.
(2) The color subcarrier should have a duty of 50%.
Duty fluctuation will affect chroma phase. Resistance-
splitting input is used in the "Application example" to
accommodate 5V
P-P
CMOS input. For other types of
input, adjust to 0.5V
P-P
at SCIN.
(3) Composite synch and burst flag pulse inputs should
conform to their respective standards, as improper tim-
ing between them can prevent the TV from displaying
color images. For input, use the TTL level and an
impedance of 8k
.
