Part Number: DS90UB947-Q1EVM
Other Parts Discussed in Thread: ALP

Tool/software:

Hi Team,

We design a solution with 947 and 948, sometimes the screen will shaking with power on.But the probability is too low to debug it.

I heard some FAE have a debugging check document, can you send this document to me?Or is any suggesttion can help me to

debug this issue?

Best regard!

Yao.

    Hi Yao,

    It is difficult to understand because the issue description is not provided in detail. Is the system using EVMs or a custom design? Did you enable PATGEN using ALP? Have you tried with the link with PATGEN via internal timing and internal PCLK from 948 and then 947? Does that work correctly?

    You can find it in the DS90UB948 under technical documentation. Pleas let me know if you have any questions further.

    Best,

    Josh
