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
≥

(P1), where P is the value selected for the prescaler.

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 RF1/RF2 phase detector
comparison frequency..
Note 11:
The synthesizer phase noise is measured with the LMX2335TMEB/LMX2335SLBEB or LMX2336TMEB/LMX2336SLBEB/LMX2336SLEEB Evaluation
boards and the HP8566B Spectrum Analyzer.
