The Low-frequency Signal Multi-channel Transceiver Design Based on Gigabit Ethernet

Now embedded system is widely used. In order to improve the acquisition rate of low-frequency signal, this paper uses xc6vlx240t board with large capacity and fast transmission rate as the core to realize the design of multi-channel low-frequency signal receiving and transmitting based on Gigabit Ethernet, completes the functional verification of high-speed Ethernet interface based on FPGA, and briefly analyzes the experimental results in time and frequency domain. The experimental results show that the experiment has achieved the basic requirements of high-speed transmission, and through the brief analysis of time domain and frequency domain of signal by MATLAB, good results have been achieved.
