Digital switch module
max. 400 Mbps | G2D70
Universal Switching
requiring ultra-high performance, high density signal
routing and distribution for digital ECL signals up to 400Mbps.
Modules can be factory configured for a maximum of 64
inputs and 64 outputs. The modules provide a full fanout
(broadcast) capacity to receive differential ECL inputs and
distribute these to any one, many, or all of the differential ECL
outputs. Standard ECL levels apply with a 50 ohm I/O environment.
The switching array is of "fixed" size and may not be expanded
in the field without additional external equipment. This
provides the most cost effective packaging solution. It is
available with a varied number of inputs and outputs. Each
I/O has a pair of either high performance coaxial SMB or SMA
connectors for each input or output channel. Each coaxial
connector provides half of the differential data signal. If a
"Triax" connector version is desired, the G2D73 modules have
this capability.
The wide bandwidth solid-state ECL switch core design provides
for high reliability and long life. For "clock and data"
applications, it is recommended that two modules be used.
One module dedicated to clock signals while the other for
the data signals. Doing so provides the best clock/data skew
performance and is more efficient switching configuration.
Each input channel is internally terminated in a resistive 50
ohm termination to -2V. Optional outputs circuits are available
to suit the application to provide the best possible routing
scheme and a minimum of signal reflections. Output circuits
are defined by the suffix designation.
