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 PLL’s loop band-width, and large enough to avoid a substantial noise contribution from the reference.
Note 3:
Continuous Lock Temperature Range is how far the temperature can drift in either direction from it’s original value at the time of the part being programmed,
before the PLL has to be reprogrammed. The action of programming the R0 register activates a calibration routine. However, if this register is not reprogrammed,
the temperature drift spec applies. Note that 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 frequecy 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.
