摘要	For ultraviolet remote sensing instrument, a CMOS spectral imaging system based on the CMOS image sensor GSENSE400 produced by Gpixel company and Virtex-4 FPGA produced by Xilinx company was realized, including driving circuits, bias and the timing control unit. When receiving the high-speed data, the conventional LVDS training method only take into account the random jitter and ignore the sample error caused by deterministic jitter. Therefore, a new training algorithm was established to improve the accuracy of transition identification by increasing a judgment of sample data correctness. A real-time window monitor method was also presented to avoid the drift of temperature and voltage in aerospace application without affecting the data transmission. By monitoring the distance between sampling edge and the edges of data window and readjusting the delay of the data paths as soon as the window enter the transition, the method held the sampling edge in the safe sampling window and ensured the high reliability of long time data receiving. The system designed is stable and reliable, the highest image data rate is 2.5 Gb/s, the temporal noise is 1.72e-, the dynamic range is 94 dB, satisfies the requirement of the space load. 2018, Science Press.
