Hi All,
It's time for another short tech article....
Many of us in in the technical community know that crossing a path
over a break in the ground/power planes on a board can have
undesirable effects. One effect sometimes overlooked is excessive
crosstalk that occurs between paths crossing the break. December's
Technical Tidbit on my site at http://emcesd.com titled "Crossing
Ground Plane Breaks, A Source of Crosstalk" presents measured data
that shows the crosstalk, even that due to a short break in a ground
plane, can be signficant.
There is lots of stuff in the middle, but if you page down to the
bottom of the page you will see the link to the article in the form of
a picture of a circuit board with a ground slit. Right above that you
will find a link to pictures from the latest IEC TC77b meeting.
