Abstract Synthetic Aperture Radar is an efficient method of remote sensing. In the real-time processing system of Synthetic Aperture Radar, the high-speed data transmission is the emphases and the difficulty all the while. Aiming at the Rocket IO Tranceiver module of Xilinx Virtex2Ⅱ PROFPGA , This paper designs a high-speed serial I/O PCB board used on SAR data transmission system. This board uses Rocket IO module in the chip fully, BREFCLK differential input reference clock, 8B/10B recoder and pre-emphasis technology etc; implements one Rocket IO transmission at 3. 125 Gb/s and multi-channel high-speed serial in terconnection. It is reliable through validated by actual system. The results of simulation and experimentation on the hardware circuit prove this method is efficien t. and can reduce the design’s complexity and board size very well.
