Part Number: AM5728
Hi, I would like to know does domain vddshv11 power on sequence has to be after vdda_usb1 and prior to vdda33v_usb1 according to figure 5-1 in AM5728 datasheet? Can it be postponed to a later sequence, such as after rstoutn?
The reason I asked is we want to supply 1.8V to vddshv11 in order to enable eMMC HS200 mode. But we meet challenge on providing this 1.8V, because on AM572x EVM design, there is no 1.8V power supply there, this means we need an additonal 1.8V regulator on our board meanwhile the output has to be meet the power on sequence. We are just afraid that it's not easy to control the 1.8V regulator output precisely in between vdda_usb1 and vdda33v_usb1? So can we just move it after rstoutn, which this should be more easy to control.
