Using Video PHY without Xilinx HDMI IP

Jump to solution

If I want to use the video PHY without the Xilinx HDMI IP how do I know how to initialize it correctly? I am just developing some HDMI IP myself, and I have generated the passthrough design. There is a lot of c code that goes with this design. What I am looking for is what I need to do the get the video PHY up and working with some TX ref clock. There doesnt seem to be any info in the manual on what needs to be done. Thanks

Hi @beandigital,

 

Note that the IP is not encrypted. You can have a look into the RTL. Usually the registers map directly with the GT registers.

The Video PHY does not support your use case.  See PG230 Page 5, under the Unsupported Features.

Well I am not really using it as a standalone unit. It just seems that Xilinx doesnt make it very easy to use it with other HDMI IP. There isnt really any explanation on how to setup the IP registers.
