Hi,

I am using an ADV7619 to receive 3840*1080 @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 DATA output.When value of Video source is 165(white,RGB=0xA5A5A5),the device  output is not fixed vlaue 0xA5A5A5A5A5A5.sometimes is0xA6A5A5A6A5A5 or 0xA5A5A6A5A5A6 or 0xA5A6A5A5A6A5.

when i use 3840*2160 @30Hz HDMI signals,the device output is also not stable.

I try to change vlue of 0x19 register of IO Map,from (0x98, 0x19, 0x80) //LLC DLL phase  to  (0x98, 0x19, 0x9F).

I try to change value of 0x14 register of IO Map,Change drive strength of the data output drivers.

But all of  them  have no effect.

4K2K @30Hz Video format and 4k1k @60Hz Video format are as shown below.all the video format are CEA-861-B standard.

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