Venu,
I think it is generally accepted that shielding traces /
guard traces (what ever you want to call them) don't
produce much shielding benefit unless pinned down with
vias every step of the way. Most of the benefit from
using guard traces is that you increase the distance
between the signal traces by putting the guard trace in.

Subject: [SI-LIST] Cross- talk vs shielding
I need a small clarification on cross-talk between the signal traces. I
studied that cross-talk
can be avoided by placing a shielding trace between two signal traces
and by grounding that shielding trace. By using this technique, is the
cross-talk can be avoided completely? or only it can be reduced by
certain amount?
Any type of inputs are welcome.
Thanks in advance.
Best Regards,
Venu
