I2C-bus controlled multistandard alignment-free
IF-PLL demodulator with FM radio
TDA9887TS
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 s (e.g. 1 and 2.2 F).
3. Condition: luminance range (5 steps) from 0% to 100%.
4. AC load: CL < 20 pF and RL >1k. 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(video) 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”.
