AD9125 alias rejection using half band filters

Hi,

 

I'm using a common DAC clock of 370MHz, for IF generation of 70MHz and 205MHz.

While generating the 205MHz, alias components are appearing at the output, which cannot be removed by and external discrete filter.

I've attached a document to explain this problem.

I would like to know, if it is possible to filter out the alias components using the half band filters in the DAC (HB1, HB2 and HB3).

 

Regards,

Vishnu
