Notes

Values of video and sound parameters can be decreased at V
P
= 4.5 V.
The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound carrier traps
(see Figs 13 to 18);
H (s)
is the absolute value of transfer function.
S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 13). B = 4.2 MHz
(M/N standard) or B = 5.0 MHz (B/G, I and D/K standard) weighted in accordance with “CCIR 567”
The intercarrier output signal at pin 11 can be calculated by the following formula taking into account the internal
video signal with 1.1 V (p-p) as a reference:
