4 2mm Hard Metric (HM) 2mm HM is the industry s most successful backplane connector system with a strong history. It is adopted by many backplane standards. Right Angle Female Receptacle ( Socket ) Vertical Male Pin Header cpci type backplane (5-row A22, B19, B22) VME 64x backplane (5-row B19) PXI backplane (5-row A22, B22) J2 J1 J1 Backplane 3U Front Plug-in board Widely available from many connector manufacturers with a vibrant supply chain 4

5 Crosstalk One of the major problems in high-speed, high density applications is Crosstalk. Increased Noise at 7 Gbps TDR TX FEXT NEXT 5

6 The 3M TM Ultra Hard Metric (UHM) Socket Connector The UHM connector offers the ability to support high-speed differential signals in 2mm HM systems without costly backplane and daughter card re-designs. The UHM connector is a shielded d HM socket, designed to be intermateable and footprint compatible to HM sockets with superior impedance control and crosstalk reduction. 6

7 Shielding of the 3M TM Ultra Hard Metric (UHM) Socket Connector The UHM socket features individual id coaxial shielding of each signal contact. This enables orientation of differential pairs in both rows and columns. 7 Vertical Contact Shielding Horizontal Contact Shielding

8 Performance Improvement by Crosstalk reduction UHM decreased noise at 7 Gbps TX NEXT TDR FEXT Increased Noise at 7 Gbps 8

21 Outlook The 3M TM Ultra Hard Metric (UHM) Socket Connectors, 5- row and 8-row, are available today. UHM B22 socket is currently defined in next generation CompactPCI PICMG 2.30 Standard Draft to support Multi-Gigabit I/O ( 3M work group member ) Work is ongoing on a UHM header for further increased system performance with the same design goals and philosophy: to have internal shielding for higher performance and optimum ground connection, but still be foot print compatible to 5+2 HM headers. 21
