Pushing the density envelope to meet next-generation
high-speed application demands, the Impact™ 100 Ohm
Backplane Connector System features data rates up to
and beyond 25 Gbps, superior signal integrity, electrical
performance and modular design
The Impact™ 100 Ohm Backplane Connector System provides data rates up
to and beyond 25 Gbps and superior signal density up to 30 pairs per cm
(80 differential pairs per inch) when using a 6-pair system. The broad-edgecoupled transmission technology enables low cross-talk noise and high signal
bandwidth while minimizing channel-performance variation across every
differential pair within the system.
Impact XTR connectors provide OEM’s a scalable solution, (managing
speed, density and cost; pay-for-performance model), without requiring
any footprint or mating backplane connector changes from legacy Impact
connectors. Impact power modules are offered in three through six pair sizes
in conventional, coplanar and mezzanine configurations with current ratings
from 60.0 to 120.0A per module.
Designed for traditional backplane and/or midplane architectures, the Impact
100 Ohm Backplane Connector System meets the growing demand for next
generation high-speed applications.

Features and Benefits
Data rates scalable up to and
beyond 25 Gbps
Support future system performance
upgrades (standard Impact 100
Ohm connectors achieve up to
25 Gbps; XTR Impact 100 Ohm
connectors achieve beyond 25
Gbps)
Broad-edge-coupled, differentialpair system on standard connectors
Superior density, low cross-talk
noise, low insertion loss and
minimal performance variation
across all high-speed channels
Broad-edge-coupled, shieldto-wafer construction on XTR
daughtercards
Improves signal integrity (SI)
without sacrificing industry-leading
density. Lowers cross-talk noise and
minimizes performance variation
compared to legacy Impact
connectors. Supports quad routing
for a reduced PCB layer count.
Footprint and mate compatible with
existing Impact 100 Ohm backplane
products. Provides option to
upgrade electrical performance
when required
Differential-pair density up to
30 pairs per cm (80 pairs per
linear inch) when using 6-pair
configurations)
High differential pair density
supports high bandwidth needs
while minimizing board and system
real-estate usage
Inline staggered interface
Reduced mating force by 50% over
competing products in the market
Bifurcated contact beams on the
daughtercard connector
Two points of contact for long-term
reliability and built-in ground-signal
sequencing
Easy-to-manage 1.90 by 1.35mm
grid
Provides PCB routing flexibility and
reduces cost
Two compliant-pin attach options
(0.39 and 0.46mm)
Provides customers ultimate
flexibility to optimize designs for
superior mechanical and electrical
performance
