nRF9151 VDD ripple specification

[Jeff Eade]

What is the permitted VDD ripple on the nRF9151?

I see " To minimize supply voltage ripple and suppress EMI coupling to and from nRF9151 VDD, keep supply network impedance at the VDD pin below 0.2 Ω from 10 kHz to 50 kHz."

And the ripple must stay above 3.0V but what is the allowed ripple?

My concern on the RX side is that it can cause de-sensitization and on the TX side it can cause spurs on the RF signal.

Hi Jeff,

The only constraint is that the VDD operating range should be 3.0V to 5.5V (this range also includes the voltage drop, ripples and spikes). The VDD voltage, including any ripple, must never drop below 3.0 V during operation.
