We're in the early architectural stages for developing a custom ASIC for
PCI-X (133MHz). Our ASIC vendor has requested from us the package
requirements for this ASIC. Our initial thoughts is that the package must be
1mm BGA, flip chip (no wire bonds!), power planes, and ground planes. My
question is how would we describe the signal traces? Do we say we desire
controlled impedance or very small RLC values for the signals so they're
electrical short? Any comments on what an ideal package for PCI-X should be
would be very appreciative. Thanks,
