FEATURES AND SPECIFICATIONS2.00 by 2.25mm (.079 by .089") Pitch 5-Row, 6-Row and 8-Row VHDM-HSD ™Module-to-BackplaneConnector SystemFeatures and Benefitss Up to 5.0 Gbps bandwidth per signal pair enables state-of-the-art system design and performance s2.00 by 2.25mm (.079 by .089”) pitch provides real signal density of 10 differential pairs for 5-row and 6-row and 15 differential pairs for 8-row per centimeter (25 and 38 pairs respectively per inch) sMinimum distance between daughtercards:– 5-row system offers 15.00mm (.591")– 6-row system offers 18.00mm (.709")– 8-row system offers 22.00mm (.866")sGround planes between signal columns provide tightly controlled impedance for rise times down to 50 picoseconds (10-90%). This ensures very low cross talk between signals within and between columnssGround pins are in the same grid as signal pins, allowing wider channels for PCB routing and traces up to 0.25mm (.010”) wides6-row or 8-row VHDM-HSD wafers can be applied to the same stiffener as standard VHDM ® 6-row or 8-row wafers. The combination of VHDM and VHDM-HSD wafers, grouped together in the same stiffener, provides cost effective solutions to different performance parametersThe Very High Density Metric High Speed Differential (VHDM-HSD) connector system has been expanded to include 5-row, 6-row and 8-row daughtercard and backplane modules. VHDM-HSD is designed for differential-pair architecture applications that require very high interconnect density and signal integrity in a single-ended configuration.The same great modularity features and components ofVHDM are provided in the VHDM-HSD. The 5-row and 6-row systems feature 2 signal pairs per column and the8-row system features 3 signal pairs per column inincrements of 10 and 25 columns. All circuits areutilized as signal circuits without the need to use some asground circuits.The daughtercard connector consists of a metal stiffener just as with the VHDM system. The system combines the signal wafers, power modules and guidance modules into one continuous connector that can be ordered as a single specific part number. The card pitch of the VHDM-HSD 8-row system is the same as the standard VHDM 8-row system, allowing both signal wafer types for single ended and differential pair to be used together. Thismodularity and design flexibility allow engineers toincorporate both connector systems on the sameplatforms. The system is based on a 2.00mm (.079")pitch and includes vertical and right angle products thatcan be configured up to 2000 circuits. The maximumlength of a daughtercard connector on a single stiffeneris 300mm (12").The backplane connectors feature headers with open ends for continuous side-to-side stacking and headers with guide pins and polarizing keys on either end to aid in proper alignment of the mating daughtercard. The power modules occupy just a small width and hold sequentially matable pins that each manage 10.0 amps of current.Molex offers application tooling for pressing VHDM-HSD connectors into PCBs as separate modules or as complete assemblies. VHDM-HSD cable assemblies are also available for connecting backplane headers to high-performance cables.Note: VHDM and VHDM-HSD are trademarks or registered trademarks of Teradyne,Inc.元器件交易网FEATURES AND SPECIFICATIONS2.00 by 2.25mm (.079 by .089") Pitch 5-Row, 6-Row and 8-Row VHDM-HSD ™Module-to-Backplane Connector SystemPress Fit Right Angle ReceptacleApplicationsThe VHDM-HSD products are used in very high speed, short rise-time, high circuit count applications connecting daughtercards to the backplane:s Network Switches s Routerss Computer Serverss Telecommunication Equipment sInternetworking DevicesORDERING INFORMATIONDaughtercard AssemblyConfiguration 5-Row 6-Row 8-Row Signal wafers, power modules and guide modules sequentiallyassigned by application VHDM-HSD wafers74670-XXXX 74880-XXXX 74680-XXXX Combination of VHDM and VHDM-HSD wafers74686-XXXX 74886-XXXX74686-XXXXBackplane Header Signal Module Standard Loaded Pin Height 0.76µm (30µ”) Gold5-Row6-Row8-Row10-Column 25-Column 10-Column 25-Column 10-Column 25-Column Open Ended4.25mm (.167”)74695-100374695-250374979-100374979-250374649-100374649-25034.75mm (.187”)74695-100174695-250174979-100174979-250174649-100174649-25015.15mm (.203”)74695-100474695-250474979-100474979-250474649-100474649-25046.25mm (.266”)74695-100274695-250274979-100274979-250274649-100274649-2502Left Guide PinNo Polarizing Key 4.25mm (.167”)74696-100374696-2503––74650-100374650-25034.75mm (.187”)74696-100174696-2501––74650-100174650-25015.15mm (.203”)74696-100474696-2504––74650-100474650-25046.25mm (.266”)74696-100274696-2502––74650-100274650-2502Left Guide Pin“A” Polarizing Key 4.25mm (.167”)74696-101374696-2513––74650-101374650-25134.75mm (.187”)74696-101174696-2511––74650-101174650-25115.15mm (.203”)74696-101474696-2514––74650-101474650-25146.25mm (.266”)74696-101274696-2512––74650-101274650-2512Right Guide PinNo Polarizing Key 4.25mm (.167”)74697-100374697-2503––74651-100374651-25034.75mm (.187”)74697-100174697-2501––74651-100174651-25015.15mm (.203”)74697-100474697-2504––74651-100474651-25046.25mm (.266”)74697-100274697-2502––74651-100274651-2502Right Guide Pin“A” Polarizing Key 4.25mm (.167”)74697-101374697-2513––74651-101374651-25134.75mm (.187”)74697-101174697-2511––74651-101174651-25115.15mm (.203”)74697-101474697-2514––74651-101474651-25146.25mm (.266”)74697-101274697-2512––74651-101274651-2512Backplane Power and Guide Components5-Row and 6-Row 8-Row Power Module 74029-600074029-8000Keying Post 74069-001074069-0010Guide Pin74076-0001/000274076-0001/0002Americas Headquarters Lisle, Illinois 60532 U.S.A.1-800-78MOLEX amerinfo@ Far East North Headquarters Yamato, Kanagawa, Japan 81-462-65-2324feninfo@ Far East South Headquarters Jurong, Singapore 65-6-268-6868fesinfo@ European Headquarters Munich, Germany 49-89-413092-0eurinfo@ Corporate Headquarters 2222 Wellington Ct.Lisle, IL 60532 U.S.A.630-969-4550Visit our Web site at /product/backplan/hsd.htmlOrder No. USA-158 Rev. 2Printed in USA/2.5K/JI/JI/2003.03©2003, MolexNote: VHDM and VHDM-HSD are trademarks or registered trademarks of Teradyne,Inc.元器件交易网。
