Hi
I am designing two boards with virtex 4 fx devices fitted. They will stac one on top of the other using a board to board connector. The spacin between boards is about 20mms. Is it critical the type of connector that use to connect the MGT links between the boards. Do I need one of thes fancy 50 ohmn connectors or can I get away with something else? Is there way to simulate the effects that the connector will have?
Cheers
Jon
