DM365: can video digital output comes simultaneously with analog output?

From the DVSDK2.10/MVL5 drivers, only one is enabled at one time. We are going to modify the driver the get both output at same time. From hardware point of view, is this possible?

    This question has been asked before, so there are a few threads that mention this idea on the forums, for example here.

    The short answer to your question is yes*, this is possible.

    The long answer is that though it is possible there is a major limitation in that there is only a single display video pipeline in the DM365, thus the timings for both analog and digital outputs will have to match perfectly, such that you would typically need some external logic (FPGA) to handle any required format conversion for your digital display. Thus, though this is technically possible, it is not practically useful for most designs, I don't believe I have ever seen both used simultaneously so it is also not a tested use case (to my knowledge).

  • Bernie is correct.

    Please also keep in mind you are limited to the standard mode of display (due to DAC limitation).
