falls within the specified range. Figure 33
and Figure 34 summarize these VCO ranges.

Figure 33 shows the boundaries of the VCO frequency ranges
over the full range of temperature and supply voltage variation
for all devices from the available population. The implication is
that multiple devices chosen at random from the population and
operated under widely varying conditions may require different
values to be programmed into CFR3<26:24> to operate at the
same frequency. For example, Part A chosen randomly from the
population, operating in an ambient temperature of 10°C with
a system clock frequency of 900 MHz may require CFR3<26:24>
to be set to 100b. Whereas Part B chosen randomly from the
population, operating in an ambient temperature of 90°C with a
system clock frequency of 900 MHz may require CFR3<26:24>
to be set to 101b. If a frequency plan is chosen such that the
system clock frequency operates within one set of boundaries
(as shown in Figure 33), the required value in CFR3<26:24> is
consistent from part to part.
Figure 34 shows the boundaries of the VCO frequency ranges
over the full range of temperature and supply voltage variation
for an individual device selected from the population. Figure 34
shows that the VCO frequency ranges for a single device always
overlap when operated over the full range of conditions.
In conclusion, if a user wants to retain a single default value for
CFR3<26:24>, a frequency that falls into one of the ranges
found in Figure 33 should be selected. Additionally, for any
given individual device the VCO frequency ranges overlap,
meaning that any given device exhibits no gaps in its frequency
coverage across VCO ranges over the full range of conditions.

External PLL Loop Filter Components
The PLL_LOOP_FILTER pin provides a connection interface to
attach the external loop filter components. The ability to use
custom loop filter components gives the user more flexibility to
optimize the PLL performance. The PLL and external loop filter
components are shown in Figure 35.
