Note 2:
Normalized Phase Noise Contribution is defined as: LN(f) = L(f) – 20log(N) – 10log(Fcomp) where L(f) is defined as the single side band phase noise
measured at an offset frequency, f, in a 1 Hz Bandwidth and Fcomp is the comparison frequency of the synthesizer. The offset frequency, f, must be chosen
sufficiently smaller then the loop bandwidth of the PLL, and large enough to avoid a substantial noise contribution from the reference.
Note 3:
Maximum Allowable Temperature Drift for Continuous Lock is how far the temperature can drift in either direction from the value it was at the time that the
R0 register was last programmed, and still have the part stay in lock. The action of programming the R0 register, even to the same value, activates a frequency
calibration routine. This implies that the part will work over the entire frequency range, but if the temperature drifts more than the maximum allowable drift for
continuous lock, then it will be necessary to reload the R0 register to ensure that it stays in lock. Regardless of what temperature the part was initially programmed
at, the temperature can never drift outside the frequency range of -40C
≤

≤
85C without violating specifications.
Note 4:
The VCO phase noise is measured assuming that the loop bandwidth is sufficiently narrow that the VCO noise dominates. The maximum limits apply only
at center frequency and over temperature, assuming that the part is reloaded at each test frequency. Over frequency, the phase noise can vary 1-2 dB, with the worst
case performance typically occurring at the highest frequency. Over temperature, the phase noise typically varies 1-2 dB, assuming the part is reloaded.
