Our design DS90UB926 to get the FPD-LINK signal. We want to get the RGB888 and pass it to the DSP. To debug DS90UB926, they bought a DS90UB929 EVB to get the LVDS source to pass to DS90UB926.
So the signal chain is (929)LVDS->(926)LVDS->RGB888.
We enable 929 pattern generator . The pattern mode is 1280x800@23 as follow:
In this mode , our dsp can get valid color bar, the video is stable, as follow:
Then we change the pattern generator mode to 1280x800@60, as follow:
In this mode, our dsp will get wrong video data, the color bar is moving as follow:
It seems two frames are interleaving.
