can you explain the DVI TMDS of 576i data processed by DVI monitor with
I would like know what is the ADI Video chip part that you are using? I could not find any details in your post. Please add the issue details clearly.
Also please mention that do you have one of our evaluation board and did you verify the issue in one of our evaluation board and observe same behavior in output results?
I ma using ADV7511W part, its DVI output is directly connected to monitor through DVI port. My input to ADV7511 is 576i ITU R BT 656 format. monitor goes to power save mode again it wakes up again goes to power save mode, this process continuous. I am no sure that the data what I am sending is proper or DVI monitor not able to display 576i resolution in BT 656 format. pl. clarify me
ofcourse I am not using any ADV7511w development board for my testing. this is my own design.
We strongly recommend using one of our evaluation boards to become familiar with the parts and the scripts required to run them.
hai Mr. Guenter,
we are in the process of procuring the ADV7511 evaluation board, mean time ,I wanted to know whether ADV7511 DVI output has impedance matching resistor inbuilt or do I need to connect it outside, because the cable length from my board to monitor is about 1.5 mtr., and I my input to ADV7511 is 640X480 resolution in Embedded EAV/SAV mode.( ITU BT R656). if impedance is required means whether series impedance( 50 ohms) is better or across differential pair ( 100 ohms) is better. pl. advice me
The ADV7511 output tmds lines are based on CML circuitry. They do no need series resistors. The load provides the pull up 50 Ohm resistors . It is designed to use 50 Ohm traces and 50 Ohm cables with 100 Ohm differential pairs. Check the reference schematic to see how it's done.
