摘要

采用Xilinx Xc6slx45t FPGA为核心处理器件,配以DDR3作为帧存,实现了一套实时CameraLink至3G-SDI视频转换电路。该电路可将CameraLink视频转换为双路独立的3G-SDI视频。同时该电路也可将CameraLink视频转换为两路独立的PAL模拟视频;具备3路422通信串口,1路232维护串口,还可以实现命令接收转发,分划字符菜单叠加,外同步及同步转发等功能。该电路尺寸为50mm×50 mm,全部功能开启后功耗约4.5 W。
        Using Xilinx Xc6slx45t FPGA as the core processing device and DDR3 memory as the frame storage, a set of real-time CameraLink to 3 G-SDI video conversion circuit was herein realized. The circuit can convert the CameraLink video to two 3 G-SDI videos. Simultaneously, the circuit can also convert the CameraLink video into two independent PAL analog videos. It has three communication serial ports compliant with 422 standard and one maintenance serial port compliant with 232 standard. Additionally, it can forward commands, add reticles and character menu, receive and forward synchronization, and realize other functions as well. The circuit size is 50 mm′50 mm, and the power consumption is about 4.5 W with all functions running.
