Video signal input level and ferrite beads for power supply

Hello.

I am considering adopting ADV7391BCPZ.

I have a few questions.

1.

I use the following power supply specs.

VDD_IO = 3.3V,  VAA = 3.3V,  VDD = 1.8V,  PVDD = 1.8V

 

Since VDD_IO = 3.3V, I plan to input 3.3V digital video signals to P0-P7.

Is my understanding correct ?

Or should I adjust the input level of P0-P7 to VDD's 1.8V ?

2.

I would like to know how to select the recommended components or constants for the fayrite beads to be inserted in the power supply line.

I will be using it in a circuit that inputs in ITU-R BT.656, 8-bit 4:2:2 YCrCb and outputs an analog signal in NTSC or PAL SD quality.

HSYNC and VSYNC pins are not used.

Regards,
