I have a strange 83.3333Hz signal riding on my 1.8V and 5.0V power buses. This is my 2nd spin of this board and this noise was not present on the 1st board. Has anyone ever had experience with this type of noise? See attached picture please.
Were you able to resolve this issue?
It was determined that the boards were manufactured incorrectly. We are respinning the boards now. 1 of 10 did work and we were able to prove most of the design.
