General Description
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 Full-
Speed (12Mbps) source. The FSUSB30 is compatible
with the requirements of USB2.0 and features an
extremely low on capacitance (C
ON
) 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 FSUSB30 contains special circuitry on the D+/ D-
pins 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 volt-
age (V
CC
). 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 switch-
ing and connector sharing in portable cell phones, PDAs,
digital cameras, printers, and notebook computers.
