ADRV9002 Power sequency

Any answer?

Hi,

As per the ADP5056 datasheet, the sequence is channel 2, channel 1 and channel 3 

and if you see the schematic, the power sequence is 1V,1.3V and 1.8V which is mentioned in the datasheet.

Channel 2 is connected to VDIG_1P0.

ADP5056_1P0V is connected to VDIG_1P0 not VDDA_1P0

What is different VDDA_1P0 and VDIG_1P0?

Which (VDDA_1P0 and VDIG_1P0)  need to turn on firt? 

This is in the user guide, pg308

I am confuse.

Channel 2 : ADP5056_1P0 connected to VDIG_1P0

Channel 1 : ADP5056_1P3 connected to VDDA_1P0

Therefore, VDDA_1P0 power up after VDIG_1P0

But data sheet show VDDA_1P0 should be turn on first.

Where does it state the VDDA_1P0 must power up first? I searched datasheet and user guide.

Channel 2 connected to ADP5056_1P0 and VDIG_1P0

Channel 1 connected to ADP5056_1P3 and VDDA_1P0

Channel 3 connected to ADP5056_1P8

Therefore, Power sequency VDIG_1P0 ,VDDA_1P0,VDDA_1P8

It is violation follow statement

Channel 2 connected to ADP5056_1P0 and VDIG_1P0

Channel 1 connected to ADP5056_1P3 and VDDA_1P0

Channel 3 connected to ADP5056_1P8

Therefore, Power sequency VDIG_1P0 ,VDDA_1P0,VDDA_1P8

It is violation follow statement

Who can answer it?
