Are there some special requirments for the input signal of TVP7002 VSYNC?
1. What's the function of the 1nF capacitor? But I found that the rising edge of VSYNC will be better when I added this 1nF capacitor espeically for complicated application environment.
2. Besides, for the Componet marked as 5V/3.3V,is it a level shifter or just a 5V or 3.3V buffer? I tested the VGA signal but the VSYNC is usually 5V.
