hi Gopalakrishnan.S,
I recommend simulation, instead of following rules-of-thumb. In my opinion,
the
different #-H rules-of-thumb say that the farther traces are from each
other, the less
likely they are to crosstalk into each other. But trace distance is not the
only factor
in crosstalk.
There are many ways to reduce crosstalk in boards. You can learn about
these
by taking a signal integrity training class, or reading through articles on
the web.
One starting place could be the archives on http://signalintegrity.com.
