features and specifications 1.85mm by 1.85mm (.073 by .073) gbx* cable assembly 74552 4-pair con?guration specifications design 4-pair con?guration provides 55 real-differential pairs per linear inch (2, 3 and 5 pair con?gurations are possible extensions) ? allowing high density with more differential pairs than similar backplane products bifurcated contact beams assure greater reliability with two points of contact to header pins ground shield for individual pairs reduces crosstalk at the mating interface for improved system performance process opposed gap-resistance welding re-?ows cable conductor into the signal contact, providing a clean electrical path zinc or aluminum die-cast backshells provide shielding protection for custom input/output backplane designs integrated stiffeners and latches provide mechanical robustness and solid mating to vertical or right- angle mating (ram) headers low-pressure, strain-relief insert molding provides strain relief for the termination area and allows tighter cable shield to conductor tolerances for better impedance control features and bene?ts gbx, the next-generation high-speed backplane interconnect cabling system, delivers over 6 gbps and signal density of 55 differential pairs per linear inch the gbx high-performance backplane cable assemblies and connectors provide the speed and density required by leading-edge backplane designs. with a native differential signaling speed of 6.0 gbps, the system is well suited for existing and future generations of xaui (10 gigabit attachment unit interface) and in?niband ? - based systems. gbx cable assemblies offer improved capabilities to current backplane cable products, with impedance matching, low pair-to-pair crosstalk, within-pair and pair-to-pair skew control and a variety of raw-cable designs to meet customer-speci?c loss budgets. cables are available in a 4-pair (column) con?guration. gbx high performance cable assemblies complement molexs existing line of gbx products. for more information on molexs extensive gbx product offering, please visit: www.molex.com/ads/gbx.html. reference information mates with: gbx right-angle male connector (series 75717) gbx standard 4-pair header (series 75235) designed in: millimeters electrical current: 1.0a dielectric withstanding voltage: 250v insulation resistance: 40 megohms min. mechanical contact insertion force: 44.48n (10.00 lbf) typical per contact contact retention to housing: 8.90n (2.00 lbf) min. per contact insertion force to pcb: 0.59n (0.13 lbf) max. per contact mating force: 0.59n (0.13 lbf) max. per contact unmating force: 0.29n (0.07 lbf) min. per contact durability: 250 cycles max. physical housing: lcp, ul 94v-0 contact: copper (cu) alloy plating: contact area 0.76 um (30u) gold (au) min. solder tail area tin (sn) underplating nickel (ni) pcb thickness: 1.60mm (.062) typical operating temperature: -55 to +105c gbx cable assembly (left), daughter card connector (right), backplane header (front) *gbx is a registered trademark of amphenol, corp. ?in?niband is a registered trademark of the in?niband trade association ?contact molex for tooling justi?cation gbx 4-pair wafer C signal view
