pll loop filter design tool

http://my.athenet.net/~multiplx/cgi-...ilter.main.cgi

I plug in my design spec into it and find it gives me differenct loop filter results from my MathCad program. I donot know which one is giving the right result.
Do you have time to make a try and give me a feedback. I found this online tool matches the result from National Loop filter design tool downloaded in this board.

Thanks.

1-How different at the results? If they are only 5 to 10 percent away, then it's quite possible that different rounding approaches are causing the difference.

2-Are you sure that component numbering referes to the same component? Take a look at the schematic and make sure you are referring to the same location in the schematic.
