DS90UB926Q-Q1: Can you help confirm if the Hardware design is really good?

Dears

Part Number is DS90UB926QSQE.

Can you help confirm if the Hardware design is really good?

It may have nothing different with the application design, but I couldn't stop worrying.

    Hi,

    it sounds good but please:

    1. please check if the L17 spec. is similar as murata's DLW21SN900HQ2L, this is TI's recommendation.

    2. the parallel output pins should be matched with correct serial resistors, 100ohms should not be optimal in your case.

    3. pls follow up the power-on sequence request in d/s.

    4. i2c bus should have external pulled-up resistors.

    regards,

    Steven
