BG95 maximum ripple Vpp

I have not been able to find the power supply’s max. allowed ripple voltage for the BG95 - do anyone know the values.
i have a smps that can operate up to 1MHZ switch. freq.

Is the value the same for CAT M1 or NBIOT or GSM ?

Do you mean the switch freq of DCDC is 1MHz?
if is, It’s ok to up to 1MHZ but need to pay more attention to the interference of DCDC switch.
