Description

The TS3USB221 is a high-bandwidth switch specially designed for the switching of high-speed USB 2.0 signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os. The wide bandwidth (1GHz) of this switch allows signals to pass with minimum edge and phase distortion. The device multiplexes differential outputs from a USB host device to one of two corresponding outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. The TS3USB221 is designed for low bit-to-bit skew and high channel to channel noise isolation. The TS3USB221 is also compatible with various standards, such as high-speed USB 2.0 (480Mbps).
