Notes
1. Values of video and sound parameters can be decreased at V
2. Level headroom for input level jumps during gain control setting.
3. This parameter is not tested during the production and is only given as application information for designing the
4. Loop bandwidth BL = 70 kHz (damping factor d = 1.9; calculated with sync level within gain control range).
5. V
6. Condition: luminance range (5 steps) from 0 % to 100 %.
7. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value on pin CVBS). B = 5 MHz
8. The intermodulation figures are defined for:
