High-speed signal transmission in the video test equipment for space camera

In order to verify and assess the reliability of high-speed serial signal transmission of space camera test equipment, a modeling and co-simulating method for high-speed signal link was proposed. Firstly, the mixed models of the high-speed serial link were established, including the high-speed transceiver simulation program with integrated circuit emphasis (HSPICE) model, the RLGC model of the bonding wire connecting the transceiver die with the solder bump, the scattering parameter model of printed circuit board (PCB) extracted by SIwave, serial ATA (SATA) connector model and SATA cable model. Then based on ADS simulation platform, the impacts of the signal link and each interconnection on the high-speed transmission were analyzed by the scattering parameter simulation in frequency domain and the eye diagram simulation in time domain. Both simulation results show that this transmission link supports the maximum data rate of RapidIO at 3.125 Gbit/s, and the measured bit error rate is less than 1×10-14. Besides, the proposed method in modeling and simulating is also suitable for all kinds of high-speed serial transmission systems. ©, 2015, Huazhong Keji Daxue Xuebao (Ziran Kexue Ban)/Journal of Huazhong University of Science and Technology (Natural Science Edition).
