Yes, 1.2 Ghz ! My first mistake !
If I don't do this now, on good opportunity, I'll proubably never do it. I have extinsive experience in schematic capture and PCB layout. I think I can "tune" the diff-pair impedance properties ok. I want to learn the details of the VIA Eden with chip set, flash memory, JTAG and SRAM and Xilinx FPGAs. Have some support and can almost picture it in my mind. Still in concept and component selection phase. A lot depends on developing this project. The client has a FPGA code writer on staff and other simular projects and test boards comming up. Could be a good long term contract. Of course, they want this first one completed too quickly.
