Operation notes
(1) Since analog RGB signals perform clamping at the
input pin, input them with a low impedance.
(2) Input a signal of duty 50% for the color subcarrier. If
the duty fluctuates, it will affect the chroma phase.
Furthermore, for the application example, a voltage-
dividing resistor is assumed for the CMOS input of 5V
P-P
.
For other input formats, regulate the SCIN pin for
0.5V
P-P
.
(3) Input the composite SYNC and burst flag pulse
according to the standard value. If the timing is off, the
TV receiver may not show any color. As well, set the
input level the same as the TTL level. The input imped-
ance is 8k
.
