Overview
The TS3USB221, produced by Texas Instruments, is a high-bandwidth switch specifically designed for the switching of high-speed USB 2.0 signals. This component is tailored for use in handset and consumer applications such as cell phones, digital cameras, and notebooks with hubs or controllers that have limited USB I/Os. The TS3USB221 features a wide bandwidth of 1 GHz, which allows high-speed signals to pass with minimal edge and phase distortion. It multiplexes differential outputs from a USB host device to one of two corresponding outputs and is bidirectional, offering little or no attenuation of the high-speed signals at the outputs.
