The FSUSB30 is a low-power, two-port, high-speed USB
2.0 switch. Configured as a double-pole double-throw
(DPDT) switch, it is optimized for switching between two
high-speed (480Mbps) sources or a Hi-Speed and FullSpeed (12Mbps) source. The FSUSB30 is compatible
with the requirements of USB2.0 and features an
extremely low on capacitance (CON) of 3.7pF. The wide
bandwidth of this device (720MHz), exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior
channel-to-channel crosstalk minimizes interference.
The FSUSB30 contains special circuitry on the D+/ Dpins which allows the device to withstand an overvoltage
condition when powered off. This device is also designed
to minimize current consumption even when the control
voltage applied to the S pin, is lower than the supply voltage (VCC). This feature is especially valuable to ultraportable applications such as cell phones, allowing for
direct interface with the general purpose I/Os of the
baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs,
digital cameras, printers, and notebook computers.

Connection Diagrams
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only.

Power-On Protection
In section 7.1.1 of the USB 2.0 specification, it notes that
USB devices must be able to withstand a Vbus short to
D+ or D- when the USB devices is either powered off or
powered on. The FSUSB30 can be successfully configured to meet both these requirements.
The USB 2.0 specification also notes that the USB
device should be capable of withstanding a Vbus short
during transmission of data. Fairchild recommends adding a 100Ω series resister between the switch VCC pin
and supply rail to protect against this case. This modification works by limiting current flow back into the VCC
rail during the over-voltage event so current remains
within the safe operating range. In this application, the
switch passes the full 5.25V input signal through to the
selected output, while maintaining specified off isolation
on the un-selected pins.
Power-Off Protection
For a Vbus short circuit, the switch is expected to withstand such a condition for at least 24 hours. The
FSUSB30 has specially designed circuitry which prevents unintended signal bleed through as well as guaranteed system reliability during a power-down, overvoltage condition. The protection has been added to the
common pins (D+, D-).
