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….. -Ray WB6TPU |
