AWR1243: power on order requirements

user5378626

Part Number: AWR1243

We know that for AWR1243 there are four types of power supply (3.3V ,1.8V,1.3V and 1.2V) . I want to know that is any power on order requirements for these types of power? If there is then what's the order?

Hello Feifei,
There is no specific order to turn on these power rails but nReset needs take up only after all power rails input are stable.
AWR1243 datasheet explains about the power supply sequencing (section 5.9.1) which you refer from this link -
