41110 Customer Reference Boards
11.2 Materi alThe following materials are used with the 41110 CRB:
•FR-4, 0.062 in. +/- .007, 1.0 oz Copper Power/GND.
•Full length PCI Raw Card (3.3V Universal) 6.2” high x 7.00” long max with ½ inch cut away.
11.3 ImpedanceMost signal layers require controlled Impedance of 60 Ω +/- 5% microstrip or stripline where
appropriate.
Differential signals for the PCI-E interface require matched 100 Ω differential termination realized
as matched 50Ω resistances referenced to ground.
