Hi,

We are doing 1080p,12 bit color deep test in HDMI ADV7623 board.

We observed the following result:

Case 1:

RX Port 6 Feet cable

TX port 6 Feet cable

The video is good in 8 bit,10 bit and 12 bit

Case 2:

RX Port 30 Feet cable

TX port 6 Feet cable

The video is good in 8 bit,10 bit and 12 bit

Case 3:

RX Port 6 Feet cable

TX port 30 Feet cable

The video is good in 8 bit,10 bit

The video is not good in 12 bit . Some noise is coming.

My questions

1) What could be the cause for video failure in 12 bit length cable?

2) is there any HDMI ADV7623 TXport length limitation?

3) Any thing needs to be check in the Hardware side.

 

Thanks,

Chandravel.
