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
(CON) of 3.9pF. The wide bandwidth of this device
(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
I/O pins for applications where the VCC supply is
powered-off
(VCC=0), which allows the device to
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
the supply voltage (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. 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.
