Based on the interchanges over the past couple days it seems that a several basic ATLAS candidates have arisen:
No LVDS on PCB
Arguments for: less expensive to fab
LVDS can be distributed with twisted pair cables
Fewer or no termination issues
4 LVDS lanes on board
Arguments for: LVDS lanes make it more general purpose for future applications
Arguments for: Fits in 4 slot Aria case
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…..
