Charge Pump Current, Example Settings
from Above Graph
Notes on Setting Charge Pump Current
The recommended range for the charge pump current
is 25
A to 300 A. Below 25 A, loop filter charge
leakage, due 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 ICS, increasing charge pump current
(ICP) increases both bandwidth and damping factor.
VCXO Gain (KO) vs. XTAL Frequency
Loop Filter Capacitor Type
Loop filters must use specific types of capacitors.
Recommendations for these capacitors can be found at
