FSUSB30
Low Power 2-Port Hi-Speed USB 2.0 (480Mbps) Switch
General Description
The FSUSB30 is a Low Power, 2-Port Hi-Speed USB 2.0
switch. This part is configured as a DPDT switch and is
optimized for switching between two Hi-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 6.5pF. The wide bandwidth of this device
(720MHz), exceeds the bandwidth needed to pass the
3
rd
harmonic, resulting in signals with minimum edge
and phase distortion. Superior channel-to-channel
crosstalk also minimizes interference.
The FSUSB30 contains special circuitry on the D+/D-
pins which allows the device to withstand an overvoltage
condition. This device is also designed to minimize cur-
rent consumption even when the control voltage applied
to the S pin, is lower than the supply voltage (V
CC
). This
feature is especially valuable to Ultra-Portable applica-
tions such as cell phones, allowing for direct interface
with the General Purpose I/Os of the baseband proces-
sor. Other applications include switching and connector
sharing in portable cell phones, PDAs, digital cameras,
printers, and notebook computers.
