ADAS3023 - power supply sequencing

I have a question about power supply sequence ADAS3023.
The data sheet has an order, and the time condition is not written.
Is the following sequence safe?

 

The whole is a single power supply system. It is designed to be powered all at once.
± 15 V => (VDDH, VSSH) => 5 V LDO => AVDD => 20 Ω => DVDD => VIO

 

Best regards

    Hi Mochi

    Please confirm if I get it right. so your  setting up  from VDDH up to VIO?  and also check if you  downloaded the latest datasheet revB. That includes power up sequence and alternative power sequencing. I'd recommend to use the recommend power up sequence in the datasheet figure46.
