Overview
The TS3USB221RSERG4 is a high-bandwidth switch designed by Texas Instruments for the switching of high-speed USB 2.0 signals. This device 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 TS3USB221RSERG4 multiplexes differential outputs from a USB host device to one of two corresponding outputs, ensuring minimal edge and phase distortion due to its wide bandwidth of 1GHz. The switch is bidirectional and offers low attenuation of high-speed signals at the outputs, making it ideal for applications requiring low bit-to-bit skew and high channel-to-channel noise isolation.
