General Description

The VSC3140 is a 144x144 asynchronous crosspoint switch, designed to carry broadband data streams. The fully non-blocking switch core is programmed through a multi-mode port in terface that allows random access programming of each input/output port. Each data output can be programmed to connect to one of the 144 inputs. The signal path is unregistered and fully asynchronous, so there are no restric tions on the phase, frequency, or signal pattern on any input.
