Hello Community,

 

I want to use a LVDS display with a resolution of 1920x1080 Pixel @60Hz (Dotclock = 148.5 MHz). The display has only a single LVDS Channel with 4 differntial data lines.

I think the limitation is the serializer clock of the LDB which must not be higher than 595 MHz. When I calculate the clock for my display (148.5 MHz Dotclock * 7 Databit = 1039.5 MHz Serializer Clock) this will not work.

 

Is this up to this point correct?

 

The solution now is to use the SPLIT mode. But then I have to use both LVDS channels of the i.MX6. One for the ODD data and one for the EVEN data. I have then a SerialzerClock of 519.75MHz, which is lower than the 595 MHz. But than I need an other display that supports the two LVDS channels.

 

Is this up to this point correct?

 

The last question is now: Where can I find the information which LVDS channel is responsible for the ODD data and which one for the EVEN data?

 

Thanks in advance,

Stephan
