GENERAL DESCRIPTION

The VSC3138 is a 40 × 40, asynchronous, crosspoint switch designed to carry broadband data streams in a variety of

applications. Its fully non-blocking switch core is programmed using a multi-mode port interface that allows random

access programming of each I/O port; each VSC3138 data output can be programmed to connect to any of its inputs. The

signal path through the device is unregistered and fully asynchronous. This means that there are no restrictions on the

phase, frequency, or signal pattern of any input.

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 that facilitates AC coupling to

the switch inputs.

The VSC3138 provides a multi-mode programming interface that allows commands to be implemented as either serial

data or multiplexed parallel data. 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. A Secondary Access Port (SAP) provides for

asynchronous readback and configuration control even while the primary programming port is in use.
