Problem with ADV7511 video out display on KC705

Jump to solution

i see the KC705 sch, there are 18bit data from 325t connect to ADV7511 8:25,it looks like AVD7511 can only display Green?  

 

i see the ADV 7511 datasheet , it can not support 18bit databus.

 

why?

Hi ,

 

  1. IN KC705 ,the ADV7511 is wired to support 1080P 60Hz, YCbCr 4:2:2 encoding via 16-bit input data mapping.
  2. Also it can be operated in both embedded syncs and seperate syncs mode.
  3. We have made it operational with YCbCr 4:2:2, 16-bit, seperate syncs format.
  4. it looks like AVD7511 can only display Green?  

NO. YCbCr 4:2:2 is also a color format like RGB(8:8:8).

 

4. However i also see 18 bit data bus on the shematic.Any Xilinx guy might give explanation to this .

 

Thanks,

Akshay
