Hi Vinod,
this is a perfect case where using a em simulation + circuit simulation would
give you all the answers

Ogg: [SI-LIST] [SI-LIST]: Trace-2-Trace Coupling Length with Intentional
Crosstalk
Hi All,
Had a query on Trace-2-Trace coupling length in case of intentional
coupling/crosstalk due to physical limitations of board.
I am having 2 stripline traces routed from Point A to Point B in multiple
layers. Ideally i would love to keep them far apart so that there is no
coupling. But due to board constraints, i don't have space to keep them
apart.
The two traces are routed with spacing of 2W where there is space and with
1W spacing in many places where W is width of the trace (in my case H & W
are same numbers in stack-up)...
So would like to know what is the allowed coupling length when the
trace-2-trace spacing comes down to 1W. Signals rise time is 250ps with
frequency being 533MHz. Data pattern can be PRBS 7 or 101010.....
Regards
Vinod A H
