1. Values of video and sound parameters can be decreased at V
P
= 4.5 V.
2. S/N is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value) at pin CVBS.
B = 5 MHz weighted in accordance with
“CCIR 567”
at a source impedance of 50
Ω.
3. Measurements taken with SAW filter G1962; VSB modulation; f
