High Speed Electronic PCB Board Design Interference is a subject need to be concerned when reverse engineering high speed circuit board, the basic idea to avoid high-frequency interference is to minimize the interference of high-frequency signal electromagnetic fields, which is also called crosstalk of printed circuit board design.
High Speed Electronic PCB Board Design Interference
You can increase the distance between the high-speed signal and the analog signal, or add ground guard/shunt traces next to the analog signal. Also pay attention to the noise interference of the digital ground to the analog ground.
And also there will be problem of signal integrity in the High Speed Electronic PCB Board Design which need to be solved; Signal integrity is basically a matter of impedance matching of PCB reverse engineering. The factors affecting the impedance matching include the signal source architecture and output impedance, the characteristic impedance of the trace, the characteristics of the load, and the topology architecture of the trace. The solution is to rely on the topology of termination and alignment.
