3.1 Muxes for USB Systems

USB is a high-speed interface that enables devices to communicate over a standard interface. Multiple USB devices can be connected to a computer, and analog muxes are used to route the USB signal to different devices or ports. Most of the latest USB applications also require charging the portable devices over the USB interface. The USB 2.0 and USB3.1 specification is for high-speed signals that require high-bandwidth and low-capacitance analog muxes.

The Niquist frequency of USB2 HS is 240 MHz, 2.5 GHz for USB3 SS Gen1 and 5 GHz for USB3 Gen2. Picking the right mux is very important to pass USB compliance tests.  For some analog muxes TI offers for USB applications, see Table 3-1.
