Hi,

I am using an ADV7619 to receive 2560*1600 @60Hz HDMI signals. Its' pixel bus is configured in 2x24-bit 4:4:4 SDR interleaved mode. The pixel bus is connected to an FPGA.

 

I have a problem, the ADV7619 is not able to produce correct VSYNC HSYNC ,DATA and DE signal. At  image1.png,"video_in[47:0]" is data output of ADV7619."video_in_vld" is DE.

the data output is not correct ,too.the HDMI source input is RED,value is 0xFF.

 

I use the file "ADV7619-VER.1.9c.txt" to configure the ADV7619.

##03 HDMI Input to ADV7619, Input Pixel Frequency > 170MHz ##
