Notes on Setting Charge Pump Current
The recommended range for the charge pump current is 25
to PCB or capacitor leakage, can become a problem. This
loop filter leakage can cause locking problems, output clock
cycle slips, or low frequency phase noise.
As can be seen in the loop bandwidth and damping factor
equations or by using the filter response software available
from IDT, increasing charge pump current (I
both bandwidth and damping factor.
