The Layout of Crystal Oscillators on PCBs: A Technical Challenge, Avoiding PCB Edges is Crucial
1. Problem Description A certain dashcam requires an external adapter for testing. During power-on testing, it was found to exceed standards, specifically at frequencies of 84MHz, 144MHz, and 168MHz. The cause of the excessive radiation needs to be analyzed, and corresponding countermeasures should be provided. The radiation test data is as follows:2. Analysis of Radiation … Read more
