The PI3USB221A 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 (1.1 GHz) 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. 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).
The USB221A offer over voltage protection for the D+/D- pins as per the USB2.0 specification. With the chip power on or off if D+/D- pins are shorted to Vbus(5V+/-5%), a less than 3.8V(typ) signal will transmit through 1D+/1D- and 2D+/2D1 output.
