Hi all,
I'm trying to design power supply for T2081 processor and i got the t1040/t2081 rdb reference design.
But i want to know whether power supply sequencing is needed or not?(as per app note attached not required but not sure)
if not then i would like to remove the associated cktry multiphase controller and the MOSFET part of the power supply section in schematics.
Please help.Thanks in advance.
Required power sequencing for the T2081 is described in the data sheet T2081 QorIQ Integrated Multicore Communications Processor, Rev. 1, 3.2 Power sequencing.
The data sheet is available at:
Hi ufedor,
Thank you for the quick response, I've following queries based on your answer:
1. The power sequencing suggested by datasheet is for USB only but we're not going to use USB in our design so should I skip the power sequencing mechanism
2. Since I'm not going using USB so what to do with related USB power supply pins (USB_SVDDx,USB_HVDDx,USB_OVDDx)? should be floated or grounded. Please suggest.
Thanks in advance.
