Loop bandwidth setting

Other Parts Discussed in Thread: LMX2594


I'm using the PLLatinum Sim for LMX2594.

When I want to get Loop filter components less than 100kHz loop bandwidth, how I calculate loop filter?

I selected "Advanced" in "Feature Level" and "4th order" in "Filter Architecture".

I typed 100kHz  in "Deign Target" box and press "Calculate Loop Filter" button.

Then it shows 113.97kHz.

I want to get less than 100kHz, so I typed 80kHz.

But the result doesn't changed (113.97kHz).

I attached a capture file of my setting. 

Please let me know how to calculate loop filter components automatically.
