Overview
The TS3USB221ARSER, produced by Texas Instruments, is a high-bandwidth switch specifically designed for the switching of high-speed USB 2.0 signals in handset and consumer applications. This device is ideal for use in cell phones, digital cameras, and notebooks with hubs or controllers that have limited USB I/Os. The TS3USB221ARSER offers a wide bandwidth, 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, ensuring little or no attenuation of the high-speed signals at the outputs.
