Re: AD9833

i Kevin,

 

I am using your spreadsheet(i.e. DDS MSB Out.xls) for AD9384 design, there is seem some bug in D2,D3,E2,E3.

I attache a sample here(see below), it has two problems:

 

1. It indicate D2=6,D3=7, but we can find out from MSB list, actual "MCLKs per Fout Period" is 8(I add one calculation in H2,H3 ).

2. obviously E2,E3 are overflow.

 

I am not sure whether the problems come from bug or what my mistake to take it.

 

In addition, when "Ideal Fout"=150hz, the "Actual Fout"=125hz, do 125Hz is  finally output of DDS while Ideal Fout=150hz?

 

Thank you!

 

Neilson
