signal conversion using a FPGA

Hello everyone

I am designing a hardware which consist of FPGA board. My aim is to 
design a display driver board which is able to drive the displays using 
HDMI and LVDS signals. I am using a HDMI receiver ADV7619 which has HDMI 
input and RGB24 out. But I also need the LVDS signal in case if displays 
support LVDS.
If I give RGB signal IN FPGA it should also give LVDS out.
My question is can a FPGA convert a RGB24 signal into LVDS after 
programming it? Or do we need any kind of adapter to do so?
the fpga I am using is artix-7 series fpga, (TE0712) 200-2C.

Should be no problem as Artix-7 series have LVDS pins available. 
Conversion is kind of digital parallel-to-serial-conversion (you need 
the protocol specifications of both, input (RGB) and output). Check that 
the FPGA you choose is able to support the LVDS at the speed your 
display requires.

Nearly any of the current FPGAs canbe choosen for this purpise since all 
of them do provide LVDS standard at their IOs nowadays.

The point with video is the TMDS conversion. You will need them for both 
directions IN and OUT.

Using those devices interconnection can even be established by SDR and 
non symmetric standard w/o LVDS.

Is that a private project?

Hello

Sorry for the delay.

Thank you very much for your information. I am much clear about the 
working.
The 7-series FPGA does have SERDES so this makes things pretty clear.

Yes it is a private project.

Regards
