Values of video and sound parameters can be decreased at V
P
= 4.5 V.
For applications without I
2
C-bus, the time constant (R
×
C) at the supply must be > 1.2
µs
(e.g. 1
Ω
and 2.2
µF).
Condition: luminance range (5 steps) from 0 % to 100 %.
AC load: C
L
< 20 pF and R
L
> 1 kΩ. The sound carrier frequencies (depending on the TV standard) are attenuated by the integrated
sound carrier traps (see
Figure 16
to
Figure 21;
H
(s) is the absolute value of transfer function).
Measurement using unified weighting filter (“ITU-T
J.61”),
200 kHz high-pass filter, 5 MHz low-pass filter and subcarrier notch filter
(“ITU-T
J.64”).
The intercarrier output signal at pin SIOMAD can be calculated by the following formulae taking into account the internal video signal
with 1.1 V (p-p) as a reference:
