Part Number: DS90UB921-Q1


Dear TI Experts,

 I am now using DS90UB921 with DS90UB940

And I‘d like to know, if by any chance, the link between 921 and 940 is not connected well suddenly,and then connented well~

Does FPDLINK  have  automatic “plug and lock” performance  that can work well again?

    Hello,

    The ub921 and UB940 is based on high speed serial link design, if any "suddenly unconnected", the link's error would be reported, such as unlock indication. pls monitor it.

    regarding the recovering issue, if it is NOT power-off, the link can be recovered between ub921 and ub940.

    regards,

    Steven
