6Gb/s 144x144 Asynchronous Crosspoint Switch Physical Layer Products VSC3140 Product Brief Features: • Per Channel Programmable Input Equalization • Per Channel Programmable Output Drive Levels • On Board PRBS Generator/ Detector • Parallel and Serial Programming Modes • Secondary Serial Access Port for Configuration and Monitoring • Non-blocking Architecture with Broadcast and Multicast Modes • Soft Power Down for Unused Channels • Boundary Scan Support for Data I/O • Integrated Temperature Sensor/Alarm • On-chip Input and Output Terminations General Description The VSC3140 is a 144x144 asynchronous crosspoint switch, designed to carry broadband data streams.
The fully non-blocking switch core is programmed through a multi-mode port interface that allows random access programming of each input/output port.
Each data output can be programmed to connect to one of the 144 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 highspeed output is a fully differential switched current driver with on-die terminations for maximum signal integrity.
A multi-mode, programming interface is provided that allows commands to be sent as serial data or multiplexed parallel data.
Unused channels may be powered down to allow efficient use of the switch in applications that require only a subset of the channels.
A secondary serial access port allows asynchronous readback and configuration control to take place while the primary programming port is in use.
Benefits: • 144x144 Inputs and Outputs Allow Creation of 3-stage Clos Switch Fabrics of up to 10368 x 10368 Array Providing up to 37 Terabits of Data Throughput • Programmable Integrated Signal Equalization (ISE) Function Improves Output Jitter and Multi-pass Performance, Reducing the Need for Inter-stage Retimers in Multi-stage Switch Fabrics Applications: • • • • • • DWDM Platform Core and Edge Router St...
