Re: ADV7513 YCrCb 422 DDR input to YCrCb 444 HDMI output

Matt,

 

 

 

Please see the original thread - it has the script file attached; in the order implemented.  As I explained in the original thread, while inputting 1080i60 on a 10-bit multiplexed 422 DDR clocked bus (bus clk = pixel clk, not 2 xpclk) and mapped to the ADV7513 D9:D0 input pins, I do get an output image but only when register 0x15 is incorrectly set for SDR bus (=0x04).  Under this condition, the monitor reports that the received format is 952x540 resolution, not 1920x1080.  And under this condition  I get an image.  I have the ability to invert the DDR input clock phase and with one phase I get incorrect color but a good image, under the other phase I get the same image with very muted colors and lots of noise running through the image.

 

 

 

When I change register 0x15=0x08 (DDR bus setting for ID=8, Style 2), I get nothing, the monitors will not recognize the video.  Under either setting for register 0x15, the PLL lock register reports a lock and no other error.

 

 

 

I have also tried CSC enabled and attempted outputting RGB444 but without any success.

 

 

 

If it would help, I can send photos of the monitor outputs.  Please let me know.

 

 

 

Regards,

 

Guy
