Description

The FSUSB46 is a bi-directional, low-power, Hi-Speed,

USB2.0 switch. Configured as a double-pole, single-

throw switch (DPST) switch, it is optimized for switching

a Hi-Speed (480Mbps) source.

The FSUSB46 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 FSUSB46 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 /OE 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. An additional

feature is the detection of the 1-1 (high/high) state on

D+/D- to signal an interrupt (INT) to the processor when

entering a dedicated charging port mode of operation.
