Abstract: Based on Field Programmable Gate Array (FPGA), two sets of CameraLink interface transfer hardware platform are designed to compare serial-parallel converter chip and CameraLink interface based on FPGA). A new method, in which on-chip debugging tool Chipscope is combined with synchronized generation module, is proposed to detect error data accurately. The results show that CameraLink interface based on FPGA uses fewer pins with higher speed transmission rates. Single port supports a maximum transfer rate of 4.31 Gbit/s when the pixel clock is 154 MHz. The CameraLink data output can drive 6 m CameraLink transmission line, with no bit error appears for long hours, and it can be used in a variety of different systems based on CameraLink interface.

Key words: information processing technology, CameraLink, field programmable gate array(FPGA), SERial and DESserial(SERDES), chipscope
