Note 4:
Some of the values in this range are illegal divide ratios (B
<
A). To obtain continuous legal division, the Minimum Divide Ratio must be calculated. Use N

Note 10:
Normalized Phase Noise Contribution is defined as : L
N
(f) = L(f) 20 log (N) 10 log (F
φ
), where L(f) is defined as the single side band phase noise
measured at an offset frequency, f, in a 1 Hz bandwidth. The offset frequency, f, must be chosen sufficiently smaller than the PLL’s loop bandwidth, yet large enough
to avoid substantial phase noise contribution from the reference source. N is the value selected for the feedback divider and F
φ
is the RF/IF phase detector
comparison frequency.
Note 11:
The synthesizer phase noise is measured with the LMX2330TMEB/LMX2330SLBEB Evaluation boards and the HP8566B Spectrum Analyzer.
