cables have problems at high data rates.
who made your cables?
we've been using cables made by gore.
what is the data rate you are sending
over xaui links? eg: you are clocking

I think the 10GBE signal has clock embedded in it, the incoming clock
should be used instead of local one. Very possibly this is already the
case, but it's worth checking.
Another guess is that there is a gounding problem and sometimes the
common-ground voltage saturates the receivers. Easy
I think what must be happening is even though your iBOB and BEE2 are
running on the same clock, the XAUI links have independent 156.25 MHz
clocks, so even though the same data rate is going in as coming out,
the data is available at the other end of the link at slightly
different times, so they dri
All,
As some of you may know, Randy & I have been working on getting
reliable data transmission across the inter-chip connections on the
BEE2. We managed to get that working reliably and have moved on to
the next problem that has reared its ugly head.
Once we got back to the point of lookin
