    Hey there,

    I would like to help, but am not entirely sure what you are referring to... DSP Builder provides the user with derived clock block and PLL clock block... both can be used in multi-rate design... If this doesn't answer your question, perhaps you can try posting a sample DSP Builder design and we can help you take a look at it?

    Hi, Yan,

    You don't really have access to the clock signals in DSP Builder. Therefore, you won't be able to connect your MUX to the derived clock block.

    Instead, you have to derive the signal yourself... Possibly some sort of counter...
