The Xilinx App Note, xapp224, suggests that it's possible to do non-source-synchronous data recovery in a spartan-3 at up to 320 Mbps (320 MHz) -- has anyone ever managed to get this or higher serial speeds working in a spartan-3 PQ208 package? I'm trying to make this work with a 100-ohm differential LVDS link and I can't seem to get my design up past 150 Mbps. I'm totally willing to enterta...

Can anyone in the know comment on what the likely order of availability of Spartan-3e parts (in sub-1000 piece quantities, not zillions) will be? I'm hoping that the 3S500E in the chipscale BGA will be one of the first; I've been waiting for a high-density FPGA in a tiny package. It's a shame that none of the Spartan-3 parts larger than the 3S50 are available in that package. Thanks, E...
