LMK1D1204: Power Supply Characteristics of LMK1D120x

Part Number: LMK1D1204
Other Parts Discussed in Thread: LMK1D1208

Hi,

In the datasheet for the LMK1D120x family of devices, there is the current consumption vs frequency graph of the LMK1D1208 and I saw the comment that the LMK1D1204 follows a similar trend. For doing estimations of typical and max power consumption, can this graph be used for both devices or is there different power supply characteristics for each device?

Thank you,

Matthew Bavier

    Hi Matthew,

    Yes you can offset the LMK1D1208 graph by ~20 mA. You can take out the ~20 from this and that would be a good estimate. 

    I noticed that datasheet also have power supply somehow omitted on the release version. I will go ahead to fix that to have the actual table there.

    I have also added data for LMK1D1204 which gives about the same estimated difference from the LMK1D1208 graph in datasheet.

     

    Best,
