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 (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 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 (VCC). 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.
