Dear Venu:
A nice discussion of the pros and cons of applying guard bands for
controlling
Crosstalk is presented in reference 1.
It seems unclear how much benefit (if any)can be gained by use of guard
bands.
Hence, it is more effective to use other means for reducing Xtalk (e.g. =
use
Striplines for eliminating forward crosstlk, increase trace separation,
decrease
trace height to reference plane, utilize termination, avoid routing over
plane
splits, etc.)
Reference 1.

Subject: [SI-LIST] Cross- talk vs shielding
I need a small clarification on cross-talk between the signal traces. I
studied that cross-talk =20
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.
