| Abstract: | This paper proposed a high speed on-board data transmission solution to meet the demands of the space data transmission. The whole design structure and the key module were illustrated. A reliable and easily implemented link proto-col was designed. Post simulation waveform along the receiving and sending direction was demonstrated. System test proved that the data transmission rate for 4 channel point to point SerDes interface could reach 2. 4Gbps. Besides, the system had good performance in band width extension and disturb-resistance, which showed promising applications in the on-board payload data transmission area. |
