VSC3144
6.5 Gbps 144 × 144 Asynchronous Crosspoint Switch
GENERAL DESCRIPTION:
The fully nonblocking switch core of the VSC3144
device is programmed using a multimode port
interface that allows random access programming of
each I/O port. Each VSC3144 data output can be
VSC3144
programmed to connect to any of its inputs. The
signal path through the device uses no registers and
is fully asynchronous. This means there are no restrictions on the phase,
frequency, or signal pattern of any input.
A high degree of signal integrity is maintained throughout the VSC3144
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 VSC3144 device can be sequential on a
port-by-port basis, or multiple program assignments can be queued and
issued simultaneously using the CONFIG bit. 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.
