snooping PCLK???

[Greg Loxtercamp <gregl@ncube.com>]

I'm in the process of designing an PCI I/O card.  I will most likely be
using the Galileo 64120 as a interface chip.  I don't believe the
Galileo part has any PCI clock output to the system that I could use as
a reference.  The problem I have is that we need to run some circuitry
on the card from the 33MHz PCI clock.  This circuitry has to be exactly
syncronous with the PCI clock...not from another on-board oscillator.  I
know that it is illegal to put two loads on the clock, so what is the
best way to handle this situation.

The system is our own.  If we limit the amount of PCI cards in the
system to two, can I put two loads on the PCI clock line?  That seems
legal, however limiting.
