About ADV7511/ADV7612

To whom it may concern,

I have a product in market which transfers data between ADV7511 and ADV7612.

There are problems which i didn't notice before, 

1. Sometimes the image becomes dark, means image data from ADV7511 becomes dark image(zero)

after passing ADV7612.

2.Sometimes the image becomes noisy(snow like noise).

To come to a solution please refer to the questions below,

1.About data transfer improvement, are there any registers that i can change settings to

improve data transfer between ADV7511 and ADV7612?

2.In ADV7511 side, are there any registers for de-emphasis?

3.In ADV7612 side,about the stability of PLL lock signal. How can i relax the

pull-in range for PLL lock signal due to the input clock jitter? And how much

jitter in the input clock can the pll lock pull-in range be relaxed?

Please it's urgent since the product is already in market.

Best regards,
