HMC832 loop filter design

I've purchased an evaluation board for HMC832.

I want to redesign the loop filter for some other PFD frequency.

But before venturing that I thought of designing the current loop filter.

That is with PFD=50MHz, CPG-1.6mA, Loop BW=75kHz.

But I'm unable to arrive at the values mentioned in the datasheet for Type2 loop filter, using ADISimPLL v 4.3.
