Based on the interchanges over the past couple days it
seems that a several basic ATLAS candidates have
arisen:
2 layer
No LVDS on PCB
Arguments for: less expensive to
fab
LVDS can be distributed with twisted pair cables
Fewer or no termination issues
4-layer
4 LVDS lanes on board
Arguments for: LVDS lanes make it more
general purpose for future applications
4 slot
Arguments for: Fits in 4 slot Aria
case
6 slot
Arguments for: We’ll probably need more
than 4 slots eventually
More general purpose appeal for other
applications
Don’t need buss extender boards
There are probably other arguments for each case which
I haven’t captured.
So it seems we need to come to concensus on which fork
to take.
From my perspective I’m thinking the 2 layer 6 slot
variant makes the most sense to me.
Let the comments/suggestions/arguments
flow…..
