Impact of Supply voltage drop

[AndreasM]

I'm working on a circuit based on nRF52810. Part of the design is an audio output that draws a high current, so the supply voltage of the NORDIC can drop to 2.8V for short time.

Are there any considerations related to the max.  clock related to the supply voltage? We intend to use an external crystal at 32MHz.

Does a drop of the supply voltage have an impact on the Bluetooth performance?

Hello, 

What is your nominal voltage? There are no specs on how much ripple you can have on the system, but we recommend below 100mV, and that you are within recommended operating conditions.  

Are there any considerations related to the max.  clock related to the supply voltage?

 No, there should not be any related considerations. What kind of scenario are you looking at? As long as you are using an external crystal, you can expect a stable clock.

Does a drop of the supply voltage have an impact on the Bluetooth performance?

 No, this should not have a major impact on the performance. The internal regulators should ensure stable performance.
