We think we can have prototypes of the dev board sent to be produced by October 1, but we don't have the time to do some of the required tasks. Since the whole thing is under LGPL anyhow, I don't imagine people would object to being asked to help.
(1) We need a test power supply circuit built and tested. We have a schematic for the power supply circuit designed. We need to build one on copper clad or something like that and test. Primarily, we need to see how much noise is in the output. If someone could build that for us, we can tell you how to measure it, or you can ship it to us for testing. (2) Need to test XP10 PLLs Does anyone have a Lattice XP10 eval board? Or can get one? We can provide code or a bitfile to download via jtag that will test the clock generation the way we intend to use it. Primarily, we need to measure jitter. We can tell you how to measure jitter on a scope, or if you can verify that it generally works, you can ship it to us so we can measure it. (3) We need a heat sink What we'd like is a rectangular heat sinc that will cover both the Xilinx 3S4000 and the Lattice XP10 chips. It's needs to be the height of a PCI board (probably), at least the width of the 4000, and whatever thickness is within PCI spec. Two options: (a) A heat sink into which a fan can be optionally inserted without violating PCI spec. (b) A heat sink that can be removed and replaced with another heat sink that has a fan embedded in it. We would need to identify BOTH parts. Each of these tasks is something that Howard would likely have to do on his own, and each could take about a week. If we can get some people to help us with these, that'll shave as much as three weeks off of our development time, giving us a chance to have a meaningful announcement by Oct 1 (in time for Ohio LinuxFest). Also, let's get a small news announcement up on like KernelTrap to get some PCB and analog engineers involved. Thanks. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
