Connector and Chip Vendors Unite to Produce a High-Performance 10 Gb/s NRZ-Capable Serial Backplane

摘要

Driving faster and faster serial data rates over copper backplanes is a challenge, given that as speed increases, so do losses, dispersion, and crosstalk. Channel losses and crosstalk decrease the signal-to-noise ratio, and they limit the data rate on the channel, as well as how densely signal pairs can be packed. They add to the need for emphasis/equalization techniques that can open up 'eyes' and make it critical to have a sensitive receiver that can reliably recover the data. As a demonstration of the serial 10 Gb/s technology, a high-performance backplane has been developed using Teradyne GbX connectors and Xilinx RocketIO embedded transceivers (which are capable of driving optics as well). This combination of low crosstalk and signal compensation supports the reliable transmission of NRZ data in excess of 10 Gb/s across a copper backplane.
