LMK00804B: LMK00804B Power sequence

Part Number: LMK00804B

Hello team,

I have a question about LMK00804B power sequence because the datasheet as below is not clear.

11 Power Supply Recommendations
11.1 Power Supply Considerations
While there is no strict power supply sequencing requirement, it is generally best practice to sequence the core supply voltage (VDD) before the output supply voltage (VDDO).


Does it means, the user should consider the power up sequence that VDD should is faster than VDDO? Or the user is not concern about power up sequence?
I would like to clarify.

Best Regards,
Akihisa Tamazaki

    Hi Akihisa,

    There is no requirement on the power up sequence for this device.

    The statement does not refer to the ramp rate of VDD and VDDO. The datasheet simply says that VDD should power up first, then VDDO afterwards. 

    Kind regards,
    Lane
