Thank you kaz!

I'll try to derive 288MHz

As a separate question.

Do you think that there is simple solution of what i want with IP Catalog FIR II core in 72MHz domain?

Thanks

The short answer is no

you can use two parallel sections as even odd samples @ 144. You will need four sub-filters, not worth it and has to be done by hand not fir compiler. After all I assume your output may have to be one stream @ 288
