The TS3USB31 is a 1:1 SPST high-bandwidth switch specially designed for the switching of high-speed USB 2.0 signals. This device comes in a small UQFN package for use in a handset or consumer applications, such as cell phones, digital cameras, and notebooks with hubs. The wide bandwidth (750 MHz) of this switch allows signals to pass with minimum edge and phase distortion. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low bit-to-bit skew and high channel-to-channel noise isolation, and is compatible with various standards, such as high-speed USB 2.0 (480 Mbps).
