TMS320F280049C: Bead-ferrite on power supply are needed ?

Colombo Carlo
Mastermind 25665 points

Part Number: TMS320F280049C

HI everybody ,

in the past control cards for other C2000   there where Bead on power supply + capacitance 

now in F280449C  there are not  :  can I design without ?

could you share more info / details on the need or not ?

thank you 

regards

Carlo

    Carlo,

    we do have Ferrite beads forming pi filters on the power rails of this design. This is an attempt to suppress noise and cross talk between the domains.

    I am not familiar with any capacitance requirements outside of our standard decoupling caps and bulk capacitors which are clearly covered in the datasheet.

    Please note that the requirements are slightly different if you are using the LDO or the internal DCDC supply.

    If I have missed your question please let me know.

    Regards,
    Cody
