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. |
