Does AD9910 requires  a power supply sequencing

Hi

 

The AD9910 requires the following four power supplies.

 

Analog Core VDD at 1.8V

Analog DAC VDD at 3.3V

Digital Core VDD at 1.8V

Digital Input/Output VDD at 3.3 V

 

Does these power supplies need to be sequenced for proper device behaviour, long term reliability and reduced inrush current.

Even if it does not require a sequencing what is the best sequencing order.

 

Thanks

Diva
