Backplane Connector Achieves Data Rates Up To 6.25 Gb/s

The VHDM H-Series very high density metric backplane connector system enables an installed base to perform at 6.25 Gb/s. The system is said to improve PCB routing and back drilling while minimizing impedance discontinuities and reducing peak cross-talk by up to 50%. The signal portion of the VHDM H-Series connector system consists of modules in increments of 10 columns by 25 columns in either six or eight rows. The daughter card connector consists of a metal stiffener that combines signal wafers, power modules, and guidance modules to make one continuous connector.  The maximum length of a single stiffener is 300 mm. The power contacts handle 10A of current per blade, delivering up to 120A per 25-mm of board edge with multiple mating levels for hot pluggable applications. MOLEX INC., Lisle, IL. (800) 786-6539.
