* Question
In order to avoid crosstalk, what are the design and routing methods that are effective during the PCB layout? |
* Answer
1) Classify the logic series of the device by function.Strict control of the bus structure.
2) The layout phase reduces the physical distance of the component. 3) Reduce the line length of the parallel wiring. 4) The device is located away from the I/O interconnect and other circuit areas that are sensitive to signal degradation and coupling.) reduce the distance of the signal layer to the reference ground. 9) Reduce the line impedance and the level of the drive signal. 10) Separate the wiring layers that must be wired in the same direction with a solid planar structure (typical floor stacking). 11) Split or isolate high noise transmitters (clocks, I/O, high speed interconnects, etc.) into different layers in a stacked distribution. |
