General Description
The FSUSB23 is a low-power, high-bandwidth analog switch specifically
designed for high speed USB 2.0 applications. The FSUSB23 features very low
quiescent current even when the control voltage is lower than the VCC
supply. This feature services mobile handset applications, allowing for direct
interface with the baseband processor general-purpose I/Os.
Typical applications involve switching in portables and consumer
applications, such as cell phones, digital cameras, and notebooks with hubs or
controllers. The wide bandwidth (>720MHz) of this switch exceeds the
bandwidth needed to pass the third harmonic, which results in signals with
minimum edge and phase distortion. Superior channel-to-channel crosstalk results
in minimal interference.
