The Research and Realization of Power Supply in High-Speed DSP System

Power supply is a difficulty in high speed electronic system design. In the process of data acquisition and processing with high-speed DSP, according to the diversity of the power supply and the complexity of the system signals, the high-speed circuit board's power supply design rules and power supply filtering methods are studied and the corresponding design rule are put forward. The Monitoring Circuit of Power Supply and Power Supply Decoupling methods are discussed. The main rules should be attention in PCB layout and design are presented. System debugging results show that the power system is stable, reliable and can meet the electromagnetic compatibility requirements.
