ADF4351 Datasheet Figure 10 question

In Figure 10 of the ADF4351 datasheet (ref Pr D), it states that the PFD is set for 25MHz, and the channel spacing is 240kHz.  Since M=25MHz/240kHz=104.167, I'm not sure how you would get 240kHz.  Can you share the M value for this plot?


Also, is there a 3rd pole in the loop filter for this plot?
