Achieve Ultra-Long-Distance Transmission PCIE2.0

PCIE2.0 as between chips and boards used for interconnects,high-performance,point-based message exchange in the new I / O interconnect technology,has been recognized as the industry standard in the computer system has been widely used.PCIE2.0 at the physical layer of serial communication based SERDES technology,data transmission rates up to 5Gbps,the total number of channels up to 32 channels.With the increase in signal frequency,signal integrity issues become increasingly prominent,attenuation,crosstalk and jitter jointly lead to serious distortion of the signal transmission distance is limited.A high-performance relay chip,high-speed serial bus for PCIE2.0 to relay the signal to achieve the long-distance transmission,and in the actual system has been verified.
