Re: Hi speed USB PCB layout

Having said that, my experience with USB chips is that they exceed the
spec's requirements by enough to give you some flexibility. Our most
recent board puts high-speed USB over a 1mm-pitch pin header to a
mezzanine board, i.e. USB chip - tracks - 1mm header - tracks -
connector, and it seems to work (the tracks are maybe 5cm long and are
impedence-matched pairs). We have always used through-hole connectors
with no problems.

Maybe a coaxial/twisted connector and cable for the D+/D- would be better ..?
