Impact™︎ backplane connector system

http://www.tycoelectronics.com/_TEincludes/ver/203/TEimages/leapfrog/te-logo.png

Our new Impactimage backplane connector system is designed for  increased speed and density to meet the future system upgrades and next  generation requirements of data networking and telecommunications equipment. The  Impact backplane system also offers our customers a value added approach of  speed, density, cost and long term reliability.
  Impact Connector

The Impact connector design system contains a unique broad-edge  coupled design which utilizes low impedance, localized ground return path in an  optimized differential pair array. Additionally, differential pairs are tightly  coupled and surrounded by ground structures to isolate the pairs, which in turn  reduces crosstalk and increases overall bandwidth performance with minimal  performance variance.
  

Backplane header construction on the Impact connector offers air pockets  selectively placed in the header floor to isolate signal pairs. The header  signal pins are straight with no forms or offsets, which increase the mechanical  strength of the pins. The mating interface features a bifurcated beam with two  points of contact with the second staggered 1 mm behind the first for maximum  reliability.
 


Pairs/InchHeader Width10 Column Diff Pairs16 Column Diff Pairs

5 Pair Impact Connector6724.8mm5080
4 Pair Impact Connector5420.75mm4064
3 Pair Impact Connector4016.7mm3048
The Impact connector offers two different hole sizes and tail lengths with the  smaller one providing optimal electrical performance. The larger hole size is  ideal for backplane applications that have a slightly larger plate through hole  and pin length for manufacturing ability of the printed circuit board.
 
Key Features
  • 25 Gb/s performance
  • 100 Ohm Impedance
  • PCB footprint available in two options for both backplane and daughtercard connectors:
    1. Option 1: 0.46 mm (.018") PTH
    2. Option 2: 0.39 mm (.0154") PTH
  • Robust daughtercard connector design to withstand connector insertion forces into PCB
  • Built in guidance available for improved mating alignment and to maximize available PCB real estate

Applications

  • The Impact connector system is ideal for high speed, backplane applications including:
    • Switches
    • Servers/Blade Servers
    • Routers
    • Storage
