Crossbow™ Signal Integrity

Up to 25 Gb/s
Demonstrated 100 Ohms ± 5% impedance across an entire link
Less than 1.5% crosstalk at 50 picoseconds

Crossbow Matrix allows designers to take advantage of all the benefits associated with orthogonal midplane architectures as it is designed so the differential pairs on each side of the midplane share vias creating a straight pass-through connection. This shared via approach combined with the Crossbow footprint, eliminates most electrical problems associated with the typical backplane via stub. This includes eliminating crosstalk in the footprint, reflections, and impedance mismatches — the Crossbow connector system has demonstrated a 100 Ohms ± 5% impedance across a full link.

Both the Crossbow Matrix and 2mm+ connectors leverage optimized trace geometries, optimized footprint patterns, and an advanced 3-D shielding technique that fully surrounds and isolates the differential signals. The results are minimal transmission loss past 10 GHz, highly matched impedance, and reduced crosstalk through the connector and the entire system.
