We have one requirement, need to translate LVDS(2.5V, detail LVDS interface as below) to MIPI CSI(Qualcomm SDM660 MIPI CSI), is that DS90UB936-Q1 can do this?

if no, is there any other solution for it?

    UB936 input is FPD-Link, it is NOT the signals as listed above.

    you can use DS90UB947 + DS90UB940 solution.

    regards,

    Thanks for reply.


    Additionally.

    1. As what you saw on above capture, this signal are not the standard LVDS signal, it have synchronizing signals LVDS_SYNC+ and LVDS_SYNC-, is it possible still use DS90UB947 + DS90UB940?

    2. Is there any solution for translating LVCOMS signal to MIPI CSI-2 signal, LVCOMS is 10 bits or 14 bits, detail interface as below capture:

    1. UB947 must accept the standard video with hs/vs, or else ub940 can't decode the syn. signal for CSI2 package. if the lvds input of ub947 is out of the video format definition, the link ub947 and ub940 can't work.
    2. sorry FPD-Link product line has no parallel to mipi translator device.
