摘要
针对大型观测设备需要远距离视频传输和控制的要求,提出了采用FPGA和TLK2501为核心器件的高带宽、高速度的光纤传输方案。详细论述了硬件系统各部分组成以及TLK2501在调试中所应该着重考虑的环节。并对已经设计完成的系统进行图像传输试验,验证了本光纤传输系统的功能。
In large astronomical telescope system,there are need to remotely transmit digital signals from the standard camera link camera to the control computer.For that,the paper carries out a high speed video signal fiber transmitting system based on FPGA.The system design mainly includes the standard camera link transforming the parallel TTL signals using TLK2501,the high speed transition between parallel signals and serial signals and fiber optical send/ receive.The system that based the scheme realizes the correct transmission of the high standard Camera Link signals,pass by the experiment.
