FAQ
Q1: Key Considerations for TCXO PCB Layout Design?
A: 1) Keep away from heat sources: Maintain distance from heat-generating components such as CPUs and power amplifiers during layout.
2)Enhance Shielding: Add a metal shield when necessary.
3)Clean Ground Plane: Provide a solid ground layer to prevent noise coupling between digital and analog grounds.
Q2: What are the hot frequency points of Suzhou Hangjing's Industrial Temperature TCXOs 2520-TC22S4 Series?
A: 40M, 38.4M, 32M, 26.48M, 25M, 26M...
