Description
FSUSB22 is a low-power, high-bandwidth switch
specially designed for applications switching high-speed
USB 2.0 signals in handset and consumer applications;
such as cell phone, digital camera, and notebook with
)
ON
hubs or controllers of limited USB I/O. The wide
bandwidth (750MHz) allows signals to pass with
minimum edge and phase distortion. Superior channel-
to-channel crosstalk results in minimal interference. It is
compatible with the USB2.0 Hi-Speed standard.
