Overview
The TS3USB221DRCR, produced by Texas Instruments, is a high-bandwidth switch specifically designed for the switching of high-speed USB 2.0 signals. It 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 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.
