Using 32MHZ internal clock for RF transmission

[levijo]

Hi,

We have used the internal clock successfully in the past in nrf5280 for 8MHz RF transmission, but when trying to do the same in nrf5340, we faced this problem:

Nordic DevZone (ticket 335301). After going back to the debug the problem, I wonder:

does the internal oscillator accurate enough for such RF transmission?

The HFINT is not accurate enough to use radio in an efficient way in nRF52 or nRF53 SoCs and it has been discussed and mentioned in this forum many times, for example here.
