Ha Ha ....gotcha... but Seriously...
Referring back to the sequence on "flower cultivation" and
to section 4.3.6.1 of the spec: The fingers are trying
to maintain impedence control via carefully spaced AC return
right at the connector. If this is really working then...
? would there be any objection to a plane split between 3V and
5V right under the edge fingers to provide a little plane/channel
to make it easier to make the 3V bypass connections without
cutting off other signal paths with 20 mil traces from edge
fingers to 3V bypass caps. It seems to me if the signals are
depending on the fingers for AC return right at the connector,
and they are coupling finger to finger, then perhaps I can do
what I want with the power plane right under the fingers. In
this case I would not need the plane to plane decoupling caps
across the split line otherwise recommended. By the time the
signals cross the plane split, they are already on the fingers
and referenced to one another.
Did I finger this wrong?
