Internal filter fo adjustment pin.
Connect to GND via the following resistor
according to the NTSC or PAL mode.
Y signal output. Capable of driving a 75
load.
Refer to Notes on Operation, Nos. 6 and 9.
Chroma signal output. Capable of driving a
75 load.
Refer to Notes on Operation, Nos. 6 and 9.
Pin for reducing cross color caused by the
subcarrier frequency component of the Y
signal. When the CVOUT pin is in use,
connect a capacitor or a capacitor and an
inductor in series between YTRAP and
GND. Decide capacitance and inductance,
giving consideration to cross color and the
required resolution.
No influence on the YOUT pin.
Refer to Notes on Operation, No. 8.
NTSC: 20k (±1%)
PAL : 16k (±1%)
