56GB/S HIGH SPEED
MEZZANINE CONNECTOR SYSTEM
The Path to 56Gb/s
OVERVIEW
The ExaMEZZ
®
connector system is designed to enable superior
25 Gb/s electrical performance and provide a path to 56Gb/s
in anticipation of further increases in bandwidth requirements
and the data rates used for high speed signaling.
ExaMEZZ
®
connectors feature a revolutionary beam-on-beam
contact interface that minimizes the residual stub for improved
signal integrity performance compared to typical blade-on-
beam contact structures and provides exceptionally low mating
force while maintaining excellent contact normal force.
Protected mating interfaces for mezzanine board connectors
also eliminate the exposed header pin field on the backplane,
which can be susceptible to damage.
Each signal wafer incorporates an innovative one-piece,
embossed ground structure to improve crosstalk performance
through 56Gb/s. The simple, functional design contributes to a
very cost-effective solution.
The ExaMEZZ
®
connector plastic body has been optimized for
mezzanine applications, with hermaphroditic mating. One part
number can be used on both boards.
FEATURES
• Capable of supporting data rates of 25Gb/s with scalable
migration path to 56Gb/s
• Unique beam-on-beam interface
BENEFITS
• Supports future system performance upgrades while
eliminating costly redesign burden
• Superior signal integrity performance by impedance
control and low cross-talk while eliminating insertion loss
resonances. Mating forces reduced by 40% compared to
traditional blade and beam designs
• Enables design flexibility
• Durable, reliable mating interface design. Eliminates
crushed contacts
• Supports both 85 and 100 Ohm applications
• Direct mechanical connection, optimizing ruggedness and SI
• Fits a large range of customer applications
• Friendly to PCB manufacturers, improving cost and yield
• Integrate high and low speed signals in the same connector
• Integrated power
• Hermaphroditic mating interface protects mating beams
• Simple efficient 92 ohm design
• Press-fit Pin Design
• Stack height range from 15 to 45mm
• 0.36mm PTH for signals and 0.5mm for grounds
• Additional signal pin per IMLA
