Hi EZ,


I am trying to convert a signal from an old computer (Amiga 500) to hdmi. I am using AD9984A, ADV7511W with an FPGA in between. I am using a SRAM as a frame buffer. Amiga outputs an analog RGB signal with horizontal frequency of 15kHz and vertical frequency of 50Hz.

I wonder how I can configure AD9984A to work with the signal described.

I found some scripts, but the closest I can come is 480i @ 60hz (I would like to have 576i @ 50Hz).
