Bottom, left to right: 75237, 75235, 75433, 75827 2 and 3-Pair Columns add to Molex’s GbX Backplane Interconnect System Offering, Delivering Speeds Up To 10 Gbps, High Density (Up to 69 Mated Differential Channels Per Inch) and is Custom Configurable Data rates up to 10 Gbps may now be achieved with the GbX 2 and 3-pair column daughtercard and backplane system. The 2 and 3-pair column system completes the GbX product offering, making it a complete solution for high-end telecommunication and datacommunication applications. The GbX connector system provides the speed, density, and low-applied cost required by leadingedge backplane applications. It is especially suited for designs that require future speed upgrades by daughtercard replacement into an existing backplane. With native differential signaling speeds up to 10 Gbps, GbX is well suited for existing and future generations of XAUI (10 Gigabit Attachment Unit Interface) and InfiniBand† based systems, in addition to those based on ATCA‡ (Advanced Telecom Computing Architecture) and OIF (Optical Internetworking Forum) chip protocols. Internetworking and telecommunication equipment engineers will benefit by the GbX connector’s ability to provide not only a high-density, low applied-cost 75650, 75370 D ifferential Daughtercard Assemblies 75670, 75660 Lite Daughtercard Assemblies 75676, 75666 H ybrid Daughtercard Assemblies 75827, 75433 Backplane Signal Headers 75861, 75649 Lite Backplane Signal Headers 75492, 75331 Backplane Power 4 and 5 Columns: 75220, 75360 D aughtercard Assemblies solution in the near term, but also by its electrical performance in upgradeable systems. Speeds of 10 75420 4-Pair Lite Gbps have been demonstrated with appropriate SERDES Daughtercard (Serializer/ Deserializer) devices and board-material Assemblies selection. This allows system architects freedom-ofdesign for faster future systems without the worry of 75426 4-Pair Hybrid backward compatibility, along with the economy of a Daughtercard common backplane for two generations of equipment. Assemblies In addition, the GbX Lite Series system provides a 75235, 75237 Backplane Signal complimentary high-density open pin field for costeffective design of slower-speed circuits along the same Headers stiffener as the standard, high-speed GbX wafers.
