I need to connect high speed lines from a Fine BGA to a connector
using differential lines. The positive and negative outputs from the FBGA
resides in row 1 and 2 of the FBGA, that means ~35 mils of difference
between the lines.
What is the right way to compensate for this difference?
I was thinking that the best way is to go strait out with from the
internal ball, while the second one (from the external row) will "pay" for
his shorter way by few turns as close as possible to the source. This way
the differential pair will be coupled together all the way to the connector.
Same for the receiver.
What do you think?
