| Abstract: | In this paper, a high-speed data acquisition system, sampling rate of which can be up to 100MSPS, can be placed within a small caliber antiaircraft artillery projectile, and it is designed by high-speed PCB. But because electromagnetic compatibility problems, power integrity problems and signal integrity problems, use the software ＂HyperLynx＂ to simulate signal Integrity before and after wiring for the memory. The Integrity analysis of pre-wiring provide PCB design guidelines, when the PCB wiring is completed, analyzing the signal integrity simulation again, the simulation results show that the system＇s transmission signals edge smooth, no overshoot, no undershoot, no ringing, which meet signal integrity requirements. |
