基于Camera Link的高速图像传输模块及时序优化设计

为了解决图像信号源卡与高速图像记录器实际测试过程中出现的误码较多、图像显示效果不佳等问题，给出了系统组成及原理，并在对发送与接收时序及误码出现原因加以细致分析后，提出了时钟相移与降频等方法对发送端的时序进行优化设计。通过实验对比优化前与优化后发送端的波形图以及数据校验结果，证明了优化后的数据传输更加稳定可靠，大大减少了误码的出现，提高了图像数据的准确率与可靠性。因此该优化方法切实有效，并且对其他高速同步数据的发送与接收具有一定的参考价值。

A High-speed Image Transmission Module Based on Camera Link and Timing Optimization Design[JZ)][HS)]

In order to solve the problems of some errors and the unbeautiful picture which appeared in the actual test of the image source card and the high-speed image recorder, the composition and principle of the system is introduced. After analyses the timing of sending and receiving and the error causes, proposed clock phase shift and frequency reduction to optimize the timing of the sender. Contrasting the waveform graphs of the sender before the optimization and after the optimization and data verify result, shows the data transmission is more stable and reliable after the optimization, greatly reduces the occurrence of the error, and improves the accuracy and reliability of the image data. Therefore the method of optimization is effective and has certain reference value for other high-speed synchronous data sending and receiving.
