Im using ADV7513 chip with the below configuration:
ycbcr 422, 480p 2x clk, de enable (VIC #15)
Tried to use bt656-ADV7842_7511-hdmi-480pi.txt (with ":8-bit bus separate syncs DE,VS,HS") without luck.
0x3E is detecting VIC#49 (480p-120, 16:9)
Where can i find script for detecting VIC #15
Do you have one of our evaluation board for ADV7511 or 7513?
Are you using any specific script from design support files to configure the board?
Did you do the test on the evaluation board and observe the same behavior?
We recommend that customers who are evaluating ADV7511/ADV7513 purchase an evaluation board like EVAL-ADV7612-7511 and work with it to get the scripts up and running
Did you try the scripts available in below threads that configures various modes of embedded syncs which includes 480p60?
no video output from ADV7513
Thank you for your reply
1) I have EVAL with ADV7513 from altera
3) I tried to find out a script for "YCbCr 422, 480p 2x clk, de enable" but could find only :

can you share script that meant VIC #15 which is "YCbCr 422, 480p 2x clk, de enable"
Sorry for the delay. We are checking with part specialist on this one and will update you soon
Have you tried probing the HS and VS lines to ensure that you are indeed not sending the chip 480p120 from your video source? Is VS toggling at 60Hz like it should be for VIC=15, or 120Hz? Is HS toggling at 31.5kHz (correct for VIC=15) or 63kHz (VIC=49)? I've run into cases before where I've modified the H/V rate in too many places and ended up getting the wrong CEA VIC as a result.
Hi every one
Thanks for reply,
I'm sending exact 60hz vsync with 31.5khz hsync, The problem is that i couldn't find how to config the parameters so the ADV7513 will support vic#15.
