Abstract：For the current status of telemetry digital converter test bench unable to simultaneously test multiple devices，it is proposed based on LVDS and Ethernet data transmission module design. The module combines FPGA，Ethernet，LVDS interface has its own merits，with FPGA as the control core，the W5300 Ethernet controller chip as based on UDP protocol for signal conversion between LVDS interfaces and Ethernet interfaces. The test results indicate that the module has a common，reliable，simultaneous testing of multiple devices and is suitable for high speed data acquisition systems and so on. The module has been successfully applied to telemetry digital test equipment.
