I am designing a display driver board. I have used a HDMI receiver ADV7619 for the same, I am using HDMI input to my board coming from PC. This receiver has RGB and YCrCb signal out. I have already defined an LVDS interface.

My question is, can i take RGB24 signal out from this receiver directly instead of using LVDS interface which I think here is not necessary.

Is it possible to interface the LVDS pinout directly to this IC.

Below I have pasted the LVDS interface that I have defined for my project. the additional pins for e.g. backlight can be ignored. The important pins are LVDS differential pairs.

Doing a text search for 'LVDS' on this datasheet turns up nothing, so I am going with "No."

  • \$\begingroup\$ Thanks, I tried the same before. But I think the signal conversion is needed \$\endgroup\$ – Ru_P Jul 8 '16 at 15:51
  • \$\begingroup\$ LVDS encodings can be tricky and vary a bit, so there would need to be a lot of configurability inside the device. When you wire up an LVDS encoder chip you know what signals are going where, which is good. \$\endgroup\$ – Daniel Jul 8 '16 at 17:47
