Receive Trace Length (Card
edge finger to 41210 Bridge	1.0” min - 6.0” max
receiver pin
Length Matching	Total allowable intra-pair length mis-match must not exceed 25 mils. Each
Length Matching	routing segment should be matched as close as possible. Total skew across all
Requirements:	lanes must be less than 20 ns. See the PCI-Express Desktop Design Guidelines
	for additional routing requirements
