ADF4252 TPC22 labeled “Phase Noise (Referred to CP Output) vs. PFD Frequency, IF Side” on pp. 10. Usually the phase noise starts out high, close-in to the carrier and then decreases as you look at higher frequency offsets. This graph shows the opposite. It starts at -168 dBc/Hz at 10kHz and goes to -142dBc/Hz at 1MHz. Am I looking at this data incorrectly?
