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
