ADV7619 Equalizer settings

Hello All,

 

Our customer has a trouble about HDMI 1.4 compliance test. Their products failed the test by ID8-7. Input signal is 1920x1080p(12bit) 222.75MHz. Signal level is 0.4Vp-p.

The customer tested 4 boards. They are same PCB and used same parts. One of four boards passed the test. But three boards were failed. As for the boards, the picture is blinking and/or displayed color despite it is black -and-white picture.

The customer is suspicious of the equalizer settings for this issue. Are there any advices for improvement this issue?

I attached their current equalizer settings.

 

Best regards,

Akira
