Study on the Optimal Design of the Communication Power Supply Circuit of the Power System of the Intelligent Computing Center
Affected by the actual transmission efficiency of the power system in the intelligent computing center,the gain margin corresponding to the communication power supply can not meet the actual demand,so the optimal design of the communication power supply circuit in the intelligent computing center power system is proposed.In the layout design stage of Printed Circuit Board(PCB),MSM8909 main chip and PM8916 power management chip are placed in the center of PCB,and the fan layout structure is constructed.In the cascade design stage,each high-speed signal layer is designed to be adjacent to a reference ground plane layer with the minimum interference between adjacent trace layers as the core;In the wiring design stage,strict grounding processing and impedance control are carried out for high-speed signals in the communication process.The test results show that the gain margin of the designed power supply circuit under different communication frequencies can meet the actual requirements.
