HSSDC 2 backplane connectors

Even smaller than previous HSSDC backplane connectors from TycoElectronics, the HSSDC 2 has been designed to meet 2.5Gbit/sInfiniBand 1x server I/O requirements as well as 2.1Gbit/s FibreChannel small form factor copper, FutureBus 3.125 and 5.0Gbit/sand small-form-factor pluggable copper module I/O.
HSSDC 2 plugsare die cast and feature a stamped latch/ground spring, impedancecontrolled PCB and seven high-speed contact pads.
The receptaclecaters for six chassis ground locations, six PCB grounding andretention contacts, four grounding contacts for cable to plug anda metal EMI/RFI shield.
The plug and receptacle use polarisationand keying.
The connector can accept cable from 22 to 30AWG andemploys an overmoulded strain relief.
It is designed for 250mating cycles and has nickel-plating on gold contacts.
Theconnector offers positive latching and will maintain 2.5Gbit/sdatarates up to 15m.
Equalised cable assemblies are alsoavailable from Tyco Electronics for 100ohm impedance InfiniBandand 150ohm impedance Fibre Channel requirements.
Backed by sevenof the computing industry's leaders - Compaq, Dell,Hewlett-Packard, IBM, Intel, Microsoft and Sun Microsystems -InfiniBand is an emerging standard that sets out to provide a newserver architecture that delivers a channel based, switchedfabric technology.
The InfiniBand architecture decouples the I/Osubsystem from memory by using channel-based point-to-pointconnections rather than a shared-bus load-and-storeconfiguration.
The new architecture is based on a 2.5Gbit/s wirespeed connection with one, four or twelve wire link widths, whichoffers scalable performance through multilink connections as wellas a host of interoperable link speeds.
The specificationsupports both copper and fibre implementations.
