Description
The FSUSB45 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 HS (480 Mbps) sources or an
HS source and a Full-Speed (12 Mbps) source.
The FSUSB45 is compatible with the requirements of
USB2.0 and features an extremely low on capacitance
(CON) of 7.0 pF. The wide bandwidth of this device
(720 MHz) 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 FSUSB45 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 SEL pin is lower than
the supply voltage (VCC). This feature is especially
valuable to mobile 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 state on D+/D- to signal an
interrupt (INT) to the processor when entering a
dedicated charging port mode of operation.
