Design of Multi-channel Payload Data Simulator Based on TLK2711

A high-speed payload data simulator based on TLK2711 is designed and implemented, which is used to simulate the interface and data of multi-channel high-speed payload for remote sensing satellites. The simulator uses PCIe Gen3 8-bit high-speed interface to receive simulated payload data, uses high-speed FPGA, DDR to schedule and process multi-channel simulated payload data in parallel, and uses six TLK2711 interfaces to transmit simulated payload data. The designed simulator has the characteristics of high speed, large storage capacity and high integration. The internal loop-back test results show that the system can realize the high-speed parallel simulation and transmission of six channel payload data, the code rate of each channel reaches 1.6 Gbps. The simulator is stable, reliable, and can be widely used in satellite test.
