Megtron6 high speed PCB needs not only high-speed components, but also genius and careful design. The importance of device simulation is the same as that of digital. In high speed system, noise is a basic consideration. High frequency will produce radiation and then interference.
The process of Meg6 high speed PCB design is usually: Layout - pre wiring simulation - change layout - post wiring simulation, and the wiring is not started until the simulation results meet the requirements.
Definition of Meg7 High speed PCB: it is generally believed that if the frequency of the digital logic circuit reaches 45,50MHz and the circuit working at this frequency accounts for a certain proportion of the whole system (such as 1amp 3), it will become a high speed circuit.
M6 high speed PCB--Generally, if the frequency of the circuit reaches or exceeds 50MHz, and the circuit working on this frequency accounts for more than 1 / 3 of the whole system, it can be called high speed circuit.
M7N high speed PCB--For digital circuits, the key is to look at the edge of the signal steepness, that is, the rise and fall time of the signal. The time when the signal rises from 10% to 90% is less than 6 times of wire delay, which is the high speed signal!
Megtron7 High speed PCB -- high speed circuit design technology has become a design method that electronic system designers must adopt. Only by using the design technology of high-speed circuit designer can the controllability of design process be realized.
