3.4 LOOP FILTER
The internal charge pump is directly connected to the integrated loop filter components. The first and second pole of the loop filter
are externally attached as shown in Figure 2. When the loop filter is designed, it must be stable over the entire frequency band,
meaning that the changes in K
from the low to high band specification will not make the loop filter unstable.
