TMS320F28388D: CM core clock frequency - F28388D

Part Number: TMS320F28388D

Hi,

My project is using F28388D chip, I configure  2 CPU1 and CPU 2 working at 192Mhz, If CPU1 and CPU2 works at 192Mhz, It is possible for CM core to work at maximum freq 125Mzh? Or CM at this case has to work at lower the freq 125Mhz ( CM core clock < 125Mhz ).?

    Hi Pham,

    CM can be independent of CPU1/CPU2 by using output of AUXPLL instead of SYSPLL but you also need to consider what other IPs you are using in your application because AUXPLLL is source of other module as well.
