Features and Benefits
Up to 5.0 Gbps bandwidth per signal pair enables
state-of-the-art system design and performance
™
2.00 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)
Minimum distance between daughtercards:
– 5-row system offers 15.00mm (.591")
– 6-row system offers 18.00mm (.709")
– 8-row system offers 22.00mm (.866")
Ground 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
columns
Ground pins are in the same grid as signal pins,
allowing wider channels for PCB routing and traces
up to 0.25mm (.010”) wide
6-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 parameters

The same great modularity features and components of
VHDM are provided in the VHDM-HSD. The 5-row and 6-
row systems feature 2 signal pairs per column and the
8-row system features 3 signal pairs per column in
increments of 10 and 25 columns. All circuits are
utilized as signal circuits without the need to use some as
ground circuits.
Molex offers application tooling for pressing VHDM-HSD
modularity and design flexibility allow engineers to
incorporate both connector systems on the same
platforms. The system is based on a 2.00mm (.079")
pitch and includes vertical and right angle products that
can be configured up to 2000 circuits. The maximum
length of a daughtercard connector on a single stiffener
is 300mm (12").
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.
