CPLD-based design and research of LVDS data transmission system

In order to solve the high-speed signal processing and transmission bottlenecks in data transfer speed distance problems, a CPLD-based high-speed LVDS bus data transfer system is designed, constructed a kind of LVDS chips, drives and high-speed adaptive equalizer for the based transmission system, the introduction of chip FIFO （FIFO） as a data buffer, the system using XILINX CPLD real-time control and monitoring, and fully taking into account that there is no synchronization of data transmission should take effective measures. Internal control procedures designed and implemented using VHDL language, reducing system complexity and cost, improved system integration and stability. Modelsim software application designed system was timing simulation, the simulation results obtained verify the design requirements.
