FSUSB42UMX

The FSUSB42 is a bi−directional, low−power, two−port,
high−speed, USB2.0 switch. Configured as a double−pole,
double−throw switch (DPDT) switch, it is optimized for switching
between any combination of high−speed (480 Mbps) or Full−Speed
(12 Mbps) sources.
The FSUSB42 is compatible with the requirements of USB2.0
and features an extremely low on capacitance (CON) of 3.7 pF.
The wide bandwidth of this device (720 MHz) exceeds the bandwidth
needed to pass the third harmonic, resulting in signals with minimum
edge and phase distortion. Superior channel−to−channel crosstalk also
minimizes interference.
The FSUSB42 contains special circuitry on the switch I/O pins
for applications w here the VCC supply is powered−of f (VCC = 0 V),
which allow s the device to withstand an over−voltage condition. This
device is designed to minimize current consumption even when
the control voltage applied to the SEL pin is low er than the supply
voltage (VCC). This feature is especially valuable to ultra−portable
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.
