FAIRCHILD FSUSB23

Revised August 2005
FSUSB23
Low Power Hi-Speed USB 2.0 (480Mbps) Switch
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 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 channel-to-channel crosstalk results in minimal
interference.
Features
O 10PA maximum ICCT current over an expanded control
voltage range (VIN = 2.6V, VCC = 3.6V)
O Lower Capacitance: Con = 9pF Typ
O 7: typical On Resistance (RON)
O 3dB bandwidth: > 720MHz
O Low power consumption (1PA maximum)
O Packaged in:
Pb-Free 10-lead MicroPak¥ (1.6mm by 2.1mm)
Pb-Free 16-lead DQFN
O 7kV I/O to GND ESD performance
Applications
O Cell phone, PDA, Digital Camera, and Notebook
O LCD Monitor, TV, and Set-top Box

Note 1: 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 rating. The Recommended Operating Conditions
tables will define the conditions for actual device operation.
Note 2: The input and output negative voltage ratings may be exceeded if the input
and output diode current ratings are observed. DC switch voltage may never exceed
4.6V.
Note 3: Control input must be held HIGH or LOW and it must not float.
