General Description
The VSC3140 is a 144x144 asynchro-
nous crosspoint switch, designed to
carry broadband data streams. The fully
non-blocking switch core is pro-
grammed through a multi-mode port in-
terface that allows random access pro-
gramming 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 sig-
nal pattern on any input. Each high-
speed output is a fully differential
switched current driver with on-die ter-
minations for maximum signal integrity.
A multi-mode, programming interface is
provided that allows commands to be
sent as serial data or multiplexed par-
allel data. Unused channels may be
powered down to allow efficient use of
the switch in applications that require
only a subset of the channels. A sec-
ondary serial access port allows asyn-
chronous readback and configuration
control to take place while the primary
programming port is in use.
Benefits:
•
144x144 Inputs and Outputs
Allow Creation of 3-stage Clos
Switch Fabrics of up to 10368 x
10368 Array Providing up to 37
