VSC3040
11 Gbps 144 × 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 × 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
Ω
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.
