I have a question regarding the pins VDDLDOD, VDDLDOA and EXTON.
As stated in the DW1000 datasheet section 7.1 the pins VDDLDOD and VDDLDOA can be supplied by 3V3 or optionally by 1V8.
However, I would like to know if it could have negative effects in terms of performance when both pins are supplied with 3V3 instead of 1V8 ?
In addition, I would like to know if VDDLDOD and VDDLDOA can be supplied independently by two different LDO regulators or if their power supply need to be somehow connected in order to be exactly the same ?
Moreover, I already saw there was a discussion about the EXTON pin in case it is not used to control a DCDC converter:
It was recommended in the thread above to leave the EXTON pin floating if it is not used. Can someone confirm that this is the appropriate practice in case the EXTON pin is not used ?
