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

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-

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.
