Values of video and sound parameters can be decreased at V
Level headroom for input level jumps during gain control setting.
This parameter is not tested during the production and is only given as application information for designing the receiver circuit.
Loop bandwidth BL = 70 kHz (damping factor d = 1.9; calculated with sync level within gain control range). Calculation of the VIF-PLL
filter can be done by use of the following formula:
where:
K
R is the loop resistor ( ); C is the loop capacitor (F); BL
V
Condition: luminance range (5 steps) from 0 % to 100 %.
S/N is the ratio of black-to-white amplitude to the noise voltage (RMS value measured on pin CVBS and tested at video black level,
‘quiet line’). Noise analyzer settings: B = 5 MHz, 200 kHz high-pass and sound carrier trap on. In case of S/N
with “ITU-T J.61” . Measurements taken for B/G standard.
The intermodulation figures are defined for:
a) f = 1.1 MHz (referenced to black and white signal) as
