Part Number: DS90UB953A-Q1
Other Parts Discussed in Thread: DS90UB954-Q1

Dear TI Experts

I am using DS90UB953 and DS90UB954， I am confused below problems,really need your help

1.I need to use six UB953, how to confirm the six UB953 to be synchronized? If I use OV SENSOR OV2755 and ISP OV495 with UB953, how to synchronize each camera?

2.What's the delay time between UB953 and UB954? Will the cable length impact the transfer time? How will it impact?

    Hi Qianqian,

    You'll have to provide the same external frame-sync to all the 3x 954s that will be connected to the 6x 953s.

    The frame-sync will be sent over GPIOs, so you can look at Table 9 and 10 in the DS90UB954-Q1 Datasheet to get an understanding of the latency.
