各位TI的工程师，你们好，
我在AWR2243的规格书中只看到了各个电源的上电时序，没有找到具体的先后时间数据，所有的电源是可以一起上电吗？
可以一起上电，在NRST复位信号拉高之前都稳定输出。请看下面的FAQ。
. What is the Wakeup/Powering sequence of the supplies in the device?
All supplies come from the PMIC without any intervention from the device, so no specific sequence is required as such; users have to just ensure that all supplies are stable before NRST is deasserted.https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/910986/faq-faq-hardware-queries-related-to-mmwave-devices
