LMX2572: PLLatinumSim, Spurious level estimation

Part Number: LMX2572
Other Parts Discussed in Thread: LMX2594,

The spur estimation function of PLLatinumSim is very useful because it even calculates the level of PFD_VCOXtalk, which is a factor inside the chip.

However, I have only one request.
In LMX2572,LMX2594 and so on with "SYNC" function, the value of Fnum and Fden of N_Divider does not become the value which reflects the included channel divide.

Could you add it in the next revision?

Could you tell me if there is a way to estimate the spurious level at Sync Enable in the current version?

  • Hi There,

    PLL Sim does support IncludedDivide in LMX2594 but not LMX2572, I will let the developer adds it back to LMX2572 asap.

    Thanks for bringing this up.
