High-Speed(25
+
Gbps) BGA Mezzanine Connectors
IT5 Series
■Flexibility
Hirose’s IT5 mezzanine connector system is
as comfortable in today’s data rates of PCIe
and XAUI as it is in tomorrow’s 25
+
Gbps
systems.
With the ability to transmit differential, single-
ended, and power through one package and
being stackable from 14 to 40mm, IT5 can
solve your interface needs for both current
and future generations.
