NX3DV221
High-speed USB 2.0 switch with enable
Rev. 2 â 9 November 2011
Product data sheet
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, such as 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).
