Voltage ripple tolerance on SYS_VIN_MV and SYS_VIN_HV

Hi,
I have designed a carrier board for the AGX XAVIER SoM.
What is the allowed maximum voltage ripple on:
SYS_VIN_MV (5V)
SYS_VIN_HV (12V)
Regards,
Yaniv.

Please refer to module datasheet, it is 22v for HV, 6V for MV.

Hi,
I didnt looked for the maximum DC voltage but the maximum AC ripple allowed,
If the ripple is not exideeng the 6V for SYS_VIN_MV and 22V for SYS_VIN_HV I’m Ok?
Please look on the picture bellow for the Maximum AC Voltage Ripple description

No threshold for such AC ripple as the carrier board design is expected to make HV and MV in the recommendation range. Also there is a Dv/Dt chapter in OEM DG for the reference design rule to protect system from voltage drop, you can refer to that to understand the related power part design on carrier board.

Hi
You have written:
" No threshold for such AC ripple as the carrier board design is expected to make HV and MV in the recommendation range. "
Since I am designing the carrier board for the XAVIER, I would like to know what is the “recommendation range”

Please read the module datasheet for Recommended Operating Conditions:
HV: 9v~20v
MV: 4.75v~5.25v
