FSUSB20
Low-Power 1-Port High-Speed USB
(480Mbps) Switch
Features
General Description
■ −30dB off isolation at 250MHz
FSUSB20 is a low-power high-bandwidth switch specially designed for switching 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
(>720MHz) of this switch allows signals to pass with minimum edge and phase distortion. Superior channel-tochannel crosstalk results in minimal interference. It is
compatible with the high-speed USB 2.0 standard.
■ −30dB non-adjacent channel crosstalk at 250MHz
■ 4.5Ω typical on resistance (RON)
■ −3dB bandwidth: >720MHz
■ Low power consumption (1µA max)
■ Control input: LVTTL compatible
■ Bi-directional operation
■ USB high-speed and full-speed signaling capability
■ Space-saving Pb-free packaging
Applications
■ Cell phone, PDA, digital camera, and notebook

Connection Diagrams
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.

3. Measured by the voltage drop between A and B pins at the indicated current through the switch. On resistance is
determined by the lower of the voltages on the two (A or B) pins.
4. Flatness is defined as the difference between the maximum and minimum value on resistance over the specified
range of conditions.
