Fairchild FSUSB23 Low power hi-speed usb 2.0 (480mbps) switch Datasheet

FSUSB23
Low Power Hi-Speed USB 2.0 (480Mbps) Switch
Features
General Description
■ 10µA maximum ICCT current over an expanded control
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 well 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 3rd harmonic which results in signals with
minimum edge and phase distortion. Superior channelto-channel crosstalk results in minimal interference.

The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the
conditions for actual device operation.
