Description

The FSUSB40 is a bi-directional, low-power, two-port,

Hi-Speed, USB2.0 switch. Configured as a double-pole,

double-throw switch (DPDT) switch, it is optimized for

switching between two Hi-Speed (480Mbps) sources or

a Hi-Speed and Full-Speed (12Mbps) source.

The FSUSB40 is compatible with the requirements of

USB2.0 and features an extremely low on capacitance

(720MHz) exceeds the bandwidth needed to pass the

third harmonic, resulting in signals with minimum edge

and phase distortion. Superior channel-to-channel

crosstalk also minimizes interference.

The FSUSB40 contains special circuitry on the switch

withstand an over-voltage condition. This device is

designed to minimize current consumption even when

the control voltage applied to the SEL pin is lower than

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 switching and connector sharing in

portable cell phones, PDAs, digital cameras, printers,

and notebook computers.
