LMK00301: LMK00301 power supply of the not used outputs

Part Number: LMK00301

Hello team,

We are using LMK00301 and in some projects we don't use certain outputs. For example, in project A, we won't use Bank_A's output. In this case, we want to don't connect power supply to VccoA. In project B, we won't use REFout's output. In this case, we want to don't connect power supply to Vccoc. 

Is there any risk of this application? Thank you very much!

BR,

Qiang

  • Hi Qiang,

    I checked internally and received the following information:

    "I don’t believe floating the unused VCCO supplies will be detrimental.  However, this is not the way we evaluated the part, so I don’t recommend doing it unless absolutely necessary."

    I hope this information helps.

    Kind regards,
    Lane
