64-Channel Data Acquisition Module Based on MLVDS

According to the demand for multi-channel and reliable high-speed data transmission of the test for environment of the rockets' launch .the article designed and developed a 64-channel data acquisition module based on MLVDS. With FPGA as the core, using VHDL to write logic control program to control data acquisition and reading process, add the CRC check arithmetic to improve the reliability, through MLVDS interface upload data to master communication module and the upper machine .The test results show that the data acquisition module is good, bit error rate is low and the transmission rate of up to reached 35 MB/S, satisfies the requirement of system design, and has been applied in rocket environment test system.
