Part Number: DS90UB933-Q1
Other Parts Discussed in Thread: DS90UB934-Q1,

Dear TI Team:
My customer need to check DS90UB933-Q1 layout rule, their PCB area maybe larger, and the FPD-LINK interface is far from the video processor, so how to place the DS90UB934-Q1, is it closer to interface connector or closer to video processor?

Thanks!

Regards!

Sorry, are you talking 933 or 934? it is better if you can put the 933 or 934 close to the connector but you also need take care of the parallel side trace length, as it would impact the system level EMC issue.

best regards,

Steven

Hi Steven:
Sorry, customer used both 933 and 934.
So should both 933 and 934 be place near the connector?
----"but you also need take care of the parallel side trace length"-Any Suggestions on not exceeding a certain length?
Thanks!

Regards!

The pcb trace is dependent on your system level EMC request. generally <~3inches are used.
