Notes
1. Values of video and sound parameters can be decreased at V
P
= 4.5 V.
2. For applications without I
2
C-bus, the time constant (R
C) at the supply must be >1.2
s (e.g. 1
and 2.2
F).
3. Condition: luminance range (5 steps) from 0 % to 100 %.
4. AC load: C
L
< 20 pF and R
L
> 1 k
. The sound carrier frequencies (depending on the TV standard) are attenuated
by the integrated sound carrier traps (see Figs 13 to 18;
H (s)
is the absolute value of transfer function).
5. S/N
W
is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value measured on pin CVBS).
