DS90UB954-Q1: Does 954 has any register like VIDEO GOOD

Hi,

Does 954 has any register like VIDEO GOOD?

Now customer use LOCK register in order to wait the data get ready, then end terminal get the data.

But the LOCK register seems not good for this function. For example, LOCK will goes high-low-high-low while camera plug-in, but data doesn't get ready during this time.

Thank you.

    Chentsu,

    Generally, it has some options which are used for this system-level resolutions:

    1. wait for ~100ms if the link is power-on

    2. Processor linked with UB954 can judge whether the video data link is good or not?

    3. UB954's internal PASS function to judge the link quality. please refer to UB954 d/s page104 on PASS_CTL (0x7D[1:0]).

    best regards,

    Steven
