These problems can lead to or directly bring the signal distortion and timing errors, incorrect data, address and control lines, as well as system errors and even system crashes, unsolved, will seriously affect the system performance, Asus n71 battery and bring immeasurable loss. The way to solve these problems depends mainly on the circuit design. PCB PCB design quality is very important, it is the optimal design concept into reality the only way. Discussed below for the high-speed DSP system reliability design of the PCB board should pay attention to certain issues. With the improvement of the DSP operating frequency, DSP and other IC components becoming smaller package intensive, usually circuit design when considering the use of multilayer laptop batteries recommended power and ground with a special layer, Asus n61jv battery and for a variety of power, for example, the DSP's I / O power supply voltage and the core supply voltage, can be used in two different power supply layer, and when considering the high cost of multilayer processing, the wiring can be more or relative key power with a specialized layer other power wiring and signal lines, but pay attention to the width of the line must be adequate. Regardless of whether the board has a dedicated ground and power planes, plus the certain and reasonably distributed capacitance between the power and ground. To save space, reduce the number of through-holes, it is recommended to use more chip capacitors. Chip capacitors on the back of the PCB board welding surface, Asus n61ja battery chip capacitors to the through-hole connection with a wide line and connected through the through-hole power, formation.PCB design, high-speed DSP system first need to consider the problem of power supply design. In power supply design, usually using the following method to solve the problem of signal integrity.
