LMK03328: LMK03328：Power OFF Sequence

Shimizu Kensuke

Part Number: LMK03328

Is there a power off sequence requirement for the LMK03328?

I saw the following article.

I would like to know if there are any requirements regarding the timing of VDD, VDDO and PDN.

Hello,

if you have all supply pins connected to the same rail, just turn it of.

If you have mixed supply rails, it is recommended to first pull down the PDN pin, then VDDOx and last VDD.

regards,

Julian
