Overview
The TS3USB221ERSER is a high-bandwidth switch designed by Texas Instruments for the switching of high-speed USB 2.0 signals. It is particularly suited for handset and consumer applications such as cell phones, digital cameras, and notebooks with hubs or controllers that have limited USB I/Os. The device features a wide bandwidth of 1 GHz, allowing 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.
