InfiniBand* Cable Assemblies
74595 4x ^{LaneLink DDR InfiniBand cable assemblies increase system speeds while improving signal quality}
and lowering overall costs
Increased industry requirements for greater system
performance and scalability led to the development
of the Dual Data Rate (DDR) specification by the
InfiniBand technology group. Molex’s DDR assemblies
provide system speeds up to 40 Gbps over 8
differential cable pairs (4x).
Molex’s DDR InfiniBand cable assemblies provide
improved cable signal integrity versus standard 4x
InfiniBand cables (Series 74506). A new paddlecard
offers improved signal integrity over the previous edge
card connector and paddlecard design. In addition,
reduced costs are achieved due
to decreased assembly time. Superior cable assembly
quality is achieved through improved manufacturing
methods and by reducing Electro Magnetic Interference
(EMI) emissions.
Molex offers a total DDR solution by providing the DDR
industry-standard interface with 4x connector options.
Recommended 4x PCB receptacles are the LaneLink
latching version, series 91804 or the LaneLink
jackscrew version, series 91803. For additional

Features and Benefits
n New paddlecard design replaces PCB straddle-
mount connector to provide improved signal
integrity versus standard 4x InfiniBand cable
assemblies (Series 74506) and lower overall
assembly cost
n Re-designed, die-cast back shell provides overall
EMI protection and reduces EMI emissions on
sides of plug
n Improved method of cable-braid capture at the
cable-plug exit ensures lower EMI emissions on rear
of plug compared to standard 4x InfiniBand cables
n Multiple latching versions available: squeeze,
lanyard and jackscrew provides greater flexibility
in system design and cable routing
n Data rates up to 5 Gbps per pair doubles standard
4x InfiniBand data rates and provides up to 40
Gbps data rate for the total DDR system
