eLCDIF synchronization with external clock

If I understand the user guide correctly, it would appear that we can set PLL5 (Video PLL) to Bypass mode and have it listen to external clock CLK_N/CLK_P instead.  While I understand we can use a VSYNC with the eLCDIF VSYNC mode, we want to actually synchronize the pixel clock as well which there is no input I can see for that, unless I am mistaken.

Does this sound correct?

Hi Rick

yes this is correct, PLL can be bypassed and use external clock CLK_N/CLK_P

instead. There is no option in eLCDIF module for exaternal pixel clock.

Best regards
