Maximum CLK speed for McBSP module in the F28335

Dror,

McBSP can operate at a maximum frequency of half that of the source clock frequency. If your CPU speed is 150MHz, you should be fine running the McBSP at 20MHz.

For more information please take a look at the McBSP reference guide http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=sprufb7b&fileType=pdf

Thanks

Hello Noah,

Is the CPU speed relevant? I would like to highlight that I wish to provide (if at all possible) the McBSP module, an external clock, that has nothing to do with non of the F28335’s clocks. So, my question is what is the maximum speed allowed for this external clock??

Thanks,

Dror

Dror,

It applies for both internal and external clock sources.

Thanks

Noah
