Usb Cable Shielding Ground at Shirley Funk blog

Usb Cable Shielding Ground. it explains that the shiled serves two contradictory functions, (1) provides the path for esd discharge, and (2) shields emi from noise of internal digital ground. The shield only needs to be. if the device is plugged in, the cable/shield ground is connected to the chassis ground of your computer and is as. The two power supply wires, the differential pair for. if you want to shield electric fields, the shield must be connected to ground at either end of the cable but only. in most applications, the usb shield should not be connected to ground (gnd). according to usb 2.0 standard, a usb cable must be made minimally of 5 conductors: place a ferrite in series with the cable shield pins near the usb connector socket to keep emi from getting onto the cable shield. you should tie the shield of the cable, to your enclosure, and if needed (as in the case of coax), you can tie the ground of your circuit to this. if the usb cable shield is connected directly to the gnd plane then the usb cable will act as an antenna, showing up on the spectrum analyzer.
