A: Generally speaking, in order not to affect the signal integrity of the analog part as much as possible, whether the regulated power supply chip is relatively clean and has a small ripple power supply, the power supply for the analog part has relatively high requirements. Whether the analog part and MCU have the same power supply, in high-circuit designs, it is recommended to separate the power supplies of the analog part and the digital part. The power supply to the digital part needs to be considered to minimize the impact on the analog circuit part.
A: The solution is to choose a router with a strong winding engine, because most of them have set constraints to control the winding method and the number of vias, and can manually adjust the difficulty of wiring, which can be effective Resolve the conflict between the two.
A: You can increase the distance between high-speed signals and analog signals, and pay attention to the noise interference of digital ground to analog ground.
A: First, the length of the two lines should be as long as possible, and second, the distance between the two lines should remain constant, that is, remain parallel. Parallel methods can be divided into two types. One is that two lines run on the same wiring layer, and the other is that two lines run on two adjacent layers above and below. Generally, the former is the most common way.
A: In high-speed digital circuits, in order to improve signal quality and reduce wiring difficulty, multi-layer boards are generally used and dedicated power layers and ground layers are allocated.
