USB2.0 interface circuit

Description: USB requires the user to provide a 5V power supply, the current of the power supply is determined according to the actual scene, and it needs to be well filtered.It is recommended to use DCDC for voltage reduction and short-circuit protection. At the same time, ESD devices must be placed on the two USB DP DN data lines.The smaller the junction capacitance is, the better it is. The ESD device option should be dedicated to USB. The varistor used in the figure is. The ferential pair cable length of the USB2.0 connected to the USB connector is less than 8inch. When the IC or module is connected to the USB2.0 board, the differential signal cable length shall not be

greater than 10inch. The differential impedance of USB cable is controlled at 90 Ω.
