Description

The FSUSB43 is a bi-directional, low-power, two-port,

high-speed, USB2.0 switch. Configured as a double-

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

switching between two high-speed (480Mbps) sources

or a high-speed and full-speed (12Mbps) source.

The FSUSB43 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 FSUSB43 contains special circuitry on the switch

I/O pins for applications where the V

powered-off (V

withstand an over-voltage condition. This minimizes

current consumption even when the control voltage

applied to the SEL pin is lower than the supply voltage

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.
