Datasheet

1. General description
The NX3DV221 is a high-bandwidth switch designed for the switching of high-speed USB
2.0 signals in handset and consumer applications. These applications could be cell
phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os.
The wide bandwidth (1 GHz) of this switch allows signal 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).
