Part Number: LMK5C23208A
Other Parts Discussed in Thread: LMK5C33414A

Hello TI,

According to snas918, the LMK5C23208A has a current consumption of 55mA per DPLL:

What pin in this current drawn from, please? VDD_DIG or VDD_IN[1:0] perhaps?

Similar uncertainty seems to exist for other parts in the clockgen family, e.g. LMK5C33414A, etc.

    Hi Bernhard,

    The current from each DPLL is mainly drawn from the pins from the respective APLL. So for example, the current consumption from DPLL3 will draw current from the VDD_APLL3 pin. This is the same for the other parts of the LMK5B/LMK5C family as well. 

    Best,
