Hey Griffin.
Also, when hooking a ROACH up in a chassis where does the power switch and LED
cables go? Could someone send me a picture or schematic of this
perhaps? Thanks.
On the clocks:
arb_clk is a configurable-frequency, internal clock derived from the
system clock using DCMs
aux_clk0 and aux_clk1 correspond to the two clock inputs near the ZDOKs
(J13 and J14) (not sure which is which)

The cables hook onto the J7 connector in the corner. You just need to follow
the silkscreen labels. The only gotcha is that you need to connect the
power switch to CHS_SW not PWR.
Hopefully this stuff will be documented properly. Some day.
Cheers,
David
