The parameters of PCB board layer, the distance between signal wires, the electrical characteristics of the driver and receiver end, and the connection mode of signal wires all have a certain influence on the crosstalk.
one is that two lines walk on the same layer (side-by-side), the other is that two lines walk on two adjacent layers (over-under). Generally, there are many ways to implement the former side-by-side.
In the actual study, we can conclude that there are four main interference, including power supply noise, transmission line interference, coupling and electromagnetic interference (EMI). Through analyzing various interference problems of high frequency PC
The reflection of the signal back to the signal source will increase the system noise, making it more difficult for the receiver to distinguish the noise from the signal,
there are still some differences between high frequency products and high speed products in the demand for plate.
Transmission delays on ground and interconnect lines in high-speed systems are also factors to be considered in system design.
PCB board depends on science and technology, naturally must not lag behind, so the layout of high frequency PCB has become the key point to discuss when we design PCB high frequency board.
The performance index of high frequency circuit directly affects the quality of the whole product. The layout and wiring of components can maximize the performance index of the circuit and achieve the design purpose of anti-interference.
When designing and wiring PCB, it is required to do as much as possible:1. If the wiring space permits, insert a ground wire or ground plane between the two lines with serious crosstalk, which can isolate and reduce crosstalk. 2. When electromagnetic fiel
PCB is also known as the Printed Circuit Board (Printed Circuit Board), it can realize the circuit connection between electronic components and function realization, is also an important part of the power supply circuit design.
High frequency circuit board is a special kind of circuit board with high electromagnetic frequency. Generally speaking, high frequency can be defined as frequency above 1GHz.
There are several parameters to consider when designing PCBS for high frequency applications. This article discusses these factors, as well as the application of high frequency printed circuit boards.
