Description
The FSUSB31 is a low-power, single-port, high-speed
USB 2.0 switch. This part is configured as a double-pole,
single-throw switch and is optimized for switching or iso-
lating a high-speed (480Mbps) source or a high-speed
and full-speed (12Mbps) source. The FSUSB31 is com-
patible 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 band-
width needed to pass the third harmonic, resulting in sig-
nals with minimum edge and phase distortion. Superior
channel-to-channel crosstalk minimizes interference.
The FSUSB31 contains special circuitry on the D+ / D-
pins that allows the device to withstand an over-voltage
condition. This device is also designed to minimize cur-
rent consumption even when the control voltage applied
to the OE pin is lower than the supply voltage (VCC). This
feature is especially valuable for mobile applications,
such as cell phones, allowing direct interface with the
general-purpose I/Os of the baseband processor. Other
applications include port isolation and switching in porta-
ble cell phones, PDAs, digital cameras, printers, and
notebook computers.
