VSC3040
11 Gbps 144 x 144 Asynchronous Crosspoint Switch
GENERAL DESCRIPTION: The VSC3040 device is an asynchronous crosspoint switch designed to carry broadband data streams in a variety of storage, video, and networking equiqment applications. Combining the 11 Gbps per port bandwidth and 144 x 144 switch matrix enables a breakthrough 1.5 Tbps capacity in a single device. The VSC3040 also integrates the Vitesse best-in-class signal integrity and EQ technology. A high degree of signal integrity is maintained throughout the device because each high-speed output is a fully differential, switched-current driver with on-die terminations. Data inputs are terminated on-die, using 100 resistors between true and complement inputs with a common connection to an internal bias source, which facilitates AC-coupling to the switch inputs. Core programming for the VSC3040 device can be sequential on a port-by-port basis, or multiple program assignments can be queued and issued simultaneously. The entire device can be initialized for straight-through, multicast, or other configurations. Unused channels can be powered down to allow efficient use of the switch-in applications that require only a subset of the available I/O channels. Power-down is enabled in the software by programming individual unused outputs with a power-down code.
VSC3040
The VSC3040 fully non-blocking switch core is programmed using a multimode port interface that allows random access programming of each I/O port. Each VSC3040 data output can be programmed to connect to any of its inputs. The signal path through the device is fully asynchronous, eliminating restrictions on the phase, frequency, or signal pattern of any input.
