Re: Block Erupter Prisma (>=1.4 T/device, 0.75-0.78 W/G, <1 BTC/T, October Shipping)
Looking at the prisma image it's pretty hard to see what's going on [...] I think it's just a low quality image
 | Pretty much. I'm sure higher quality pictures will pop up as people get these in hand (asicminer could take some themselves, of course). Here's some different angles, but they're really not that much clearer  |
It does look like a lot of buffer ICs (or something) from that picture and there are certainly caps, I can't really tell what's on the other side of the chips though... I'm not certain of the exact way that these are being hooked up, but the core voltage is somewhere between 0.55 and 0.88 V, and 16 in series under 12V would be 0.75V per chip, which would be reasonable. Maybe on the other side of the chips are low power bucks to generate the correct I/O voltage for each chip (1.8V above whatever ground level is).
Interesting, at any rate.
