Other Parts Discussed in Thread: SN65DP159

Hello, Do we have a device or reference design that can convert eDP or DDI to DVI?
Thanks!

Best regards, Patrick

    Yes, you can convert eDP to DVI with the SN65DP159, but the eDP source will have to output DP++ for device to convert it to DVI.

    Hello Michael,


    I'm working with a carrier board using a E3900 processor from Intel.

    I have the choice between an eDP source or DDI source to feed a DVI monitor.

    What you are saying is that I should ask the manufacturer if the eDP source outputs DP++, is that the only condition ? In this case, does the AUX signal is used as the DDC interface for DVI ?


    Could this work for a DDI source ? I thought at first eDP and DP were electrically equivalent but apparently it isn't the case. All of these formats are a little confusing.

    Best regards,
    Adrien

    Hello,
    The source must support the DP++ because that is the only way the DP159 can convert the eDP protocal to DVI. The source should also support clock stretching on the source. I suggest you thoroughly read the DP159 datasheet.

    The DP159 cannot work with a DDI source. The difference between eDP and DP are the signal levels.
