Notes
1. Values of video and sound parameters can be decreased at VP = 4.5 V.
2. For applications without I2C-bus, the time constant (R × C) at the supply must be >1.2 µs (e.g. 1 and 2.2 µF).
3. Condition: luminance range (5 steps) from 0 % to 100 %.
4. AC load: CL < 20 pF and RL > 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/NW is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value measured on pin CVBS).
B = 5 MHz weighted in accordance with “CCIR 567”.
