ADV7441A HDMI equalization tweaking

Hi all,

 

Right now I'm using what ADI reccomend for setting the equalization, for TMDS frequency  < 160 MHz

 

User Map 2

62 F0 10

62 F1 0F

62 F4 20

 

The result is fairly good, yet for some weak sources or longer cable we start seeing noise...  and we're interest in tweaking the equalization rather than using above ADI recommendation.

 

The question is what are those registers meaning? What dB .... compensation?

 

TIA,

Outcomes
