DS90UB964-Q1: DS90UB964-Q1

Hi,

When we use TI's ds9ub913 and ds90ub964 serial link, we have the phenomenon of video drop frame and image shaking (), after a long period of debugging,
I found that the TX PORT1's FV signal disappears()
What's wrong?

Our programme is as follows:
OV10640----->913------->964-------->OV490------->TX1
thanks

    Hi Cloud,
    Have you checked the FV/LV timing? as described in d/s page24, to prevent false detection of FrameValid, FV must be asserted for a minimum number of clocks prior to first video line to be considered valid.
    btw, how is UB964 configured to CSI forwarding? sync.?

    best regards,
    Steven
