Four preleading contacts (1.5 mm) serve
to pre-load the transmit and receive logic
so that the bus will not experience glitches
during
live insertion of new cards into the
backplane.
System description
The advantages of in detail
Backplane connector terminations
are designed in solderless
press-in
technology.
The connector can be installed without
any special tooling using economical
flat dies for high speed insertion.
User-defined pins in the outer rows can be used for
application specific functions such as
additional I/O.
Configured as a shield to provide larger ground return
paths, they assure for higher
data transfer rates:
• Up to 320 MByte/s for asynchronous signals
(VMEbus)
• Up to 1.25 GB/s for Gigabit Ethernet
• Up to 3.125 GB/s for differential signals
(serial, point-to-point)
Proprietary bus systems can utilise
the new contact rows to optimise
signal-to-ground ratios and improve
system speed.
