How to Protect the High-Speed Data Interfaces of a Bone Densitometer from ESD and Noise Interference?

For high-speed data interfaces such as USB and Ethernet, the protection design must balance discharging electrostatic current and maintaining signal integrity. Multi-channel ESD protection arrays with ultra-low clamping voltage and extremely low parasitic capacitance should be selected and directly connected in parallel to the data lines to provide a low-impedance discharge path for electrostatic discharge. Additionally, common-mode chokes can be connected in series to suppress common-mode electromagnetic interference on the data transmission lines. This combined approach effectively prevents signal attenuation and distortion, ensuring stable and reliable data transmission.
