Automotive product PCB design case

[plate type]

Digital, analog, RF hybrid board

[Contacts]

5800

[Floor]

8th floor

[highest signal rate]

800 Mbit / s

[difficult]:

1, space is limited, the motherboard involves more functions, digital, analog, RF mixing, layout difficulties;

2. Transient voltage and static interference should be considered when designing wiring;

[Our countermeasures]:

1. At the beginning of the design, combined with our company's experience, digital, analog and RF modules are divided in a single space, they do not interfere with each other;

2, communicate with customers to optimize the principle, such as increase ESD, FU, storage capacitors, etc., GND to do single point split, and finally the product is put into production.

The overall layout of the layout:

Automotive product PCB

The wiring design is as follows:
