LMX2581: power down mode

Part Number: LMX2581

Hi Team,

Since LMX2581 has 2 power down mode, full power down and partial power down, what are the power consumption in these two mode?

If ICCpd is the current consumption in full power down mode?  And what's the current in partial power down mode?

Thank you.

    Full powerdown corresponds to IccPD spec (7mA).
    Partial powerdown depends on which blocks are enabled based on register settings. You can sum each IccX current in Table 7.5 for each enabled block. IccCore spec corresponds to PLL, VCO, and control blocks. IccRFout corresponds to each output buffer. IccVCO_DIV corresponds to VCO divider. Also, see section 10.1 for current per supply pin.

    Power consumption = Vcc * (Total sum of Icc currents)
