Part Number: CC2652R

Hi Team ,

           Can not find any informations about the requirement of Ripple voltage in VDDS of CC2652R . Can you help to offer the information ? The VDDS will supplied by 

battery directly and It's important for customer to know the requirement . Thank you!

    Hi,

    Ripple voltage requirement varies with the noise/switching frequencies.

    So, we recommend to copy and  use our Reference design for Power supply filtering.

    Thanks,

    Hi PM , 

           Customer has copied TI reference disign in their sch. Due to the VDDS is supplied by a battery directly and different battery will produce different ripple voltage.If TI can guide the limits of ripple voltage in VDDS. Customer can choose proper battery to guaranteed system stability. Thank you!

    Hi,

    If they are using Battery they should not have any issue with Ripple because the Batteries are source of clean Power supply. That means Batteries don't generate any ripple.

    We recommend to use our Reference Design in order to achieve data sheet performance.

    If the observe any issues then can send their Schematic in PDF and PCB Layout in Gerber format for review.

    You can request the Design Review by using a link on TI website (Please check under CC2652 Product page).

    Thanks,

    PM
