| Abstract: | Using Xilinx Xc6slx45t FPGA as the core processing device and DDR3 memory as the frame storage, a set of real-time CameraLink to 3G-SDI video conversion circuit was herein realized. The circuit can convert the CameraLink video to two 3G-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. |
