Fairchild FSUSB22MTC Low power 2 port hi-speed usb 2.0 (480mbps) switch Datasheet

Revised June 2005
FSUSB22
Low Power 2 Port Hi-Speed USB 2.0 (480Mbps) Switch
General Description
Features
FSUSB22 is a low power high bandwidth switch specially
designed for applications of the switching of high speed
USB 2.0 signals in handset and consumer applications
such as cell phone, digital camera, and notebook with hubs
or controllers of limited USB I/O. The wide bandwidth
(750MHz) of this switch allows signals to pass with minimum edge and phase distortion. Superior channel-to-channel crosstalk results in minimal interference. It is
compatible with USB2.0 Hi-Speed standard.
■ 40dB OFF Isolation at 250MHz
■ 40dB non-adjacent channel crosstalk at 250MHz
■ 4.5: typical On Resistance (RON)
■ 3dB bandwidth: 750MHz
■ Low power consumption (1uA max)
■ Control input: TTL compatible
■ Bidirectional operation
■ USB Hi-Speed and Full Speed signaling capability
Applications
• Cell phone, PDA, digital camera, and notebook

Note 2: 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 3: The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 4: Unused control inputs must be held HIGH or LOW. They may not
float.

Note 6: 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.
Note 7: Flatness is defined as the difference between the maximum and minimum value On Resistance over the specified range of conditions.
