VSC3172 Gbps 72 x 72 Asynchronous Crosspoint Switch The VSC3172 is a 72 x 72 asynchronous crosspoint switch, designed to carry broadband data streams. The fully non-blocking switch core is programmed through a multimode port interface that allows random access programming of each input and output port. A high degree of signal integrity is maintained throughout the device by fully differential signal paths. Programmable input EQ and output pre-emphasis settings enable maximum customization for the application. Each data output can be programmed to connect to one of the inputs. The signal path is unregistered and fully asynchronous, so there are no restrictions on the phase, frequency, or signal pattern on any input. Each high-speed output is a fully differential switched current driver with on-die terminations for maximum signal integrity.

Gbps 72 x 72 Asynchronous Crosspoint Switch

The VSC3172 is a 72 x 72 asynchronous crosspoint switch, designed to carry broadband data streams. The fully non-blocking switch core is programmed through a multimode port interface that allows random access programming of each input and output port.

A high degree of signal integrity is maintained throughout the device by fully differential signal paths. Programmable input EQ and output pre-emphasis settings enable maximum customization for the application.

Each data output can be programmed to connect to one of the inputs. The signal path is unregistered and fully asynchronous, so there are no restrictions on the phase, frequency, or signal pattern on any input.

Each high-speed output is a fully differential switched current driver with on-die terminations for maximum signal integrity. Its multimode programming interface allows commands to be sent as serial data or as multiplexed parallel data. Core programming can be sequential on a port-by-port basis, or multiple program assignments can be queued and issued simultaneously.

Unused channels may be powered down to allow efficient use of the switch in applications that require only a subset of the channels. Power-down is enabled in software by programming individual unused outputs with a power-down code.
