WAS7227Q
USB High speed (480Mbps), DPDT Analog Switch
Http//:www.sh-willsemi.com
Descriptions
The WAS7227Q is a high performance, double
pole double throw (DPDT) CMOS analog switch that
operates from a single +2.5V to +4.5V power supply.
The WAS7227Q is designed for switching of
high-speed USB2.0 signals in handset and consumer
applications, such as cell phones, digital cameras, and
notebooks with hubs or controllers with limited USB
I/Os.
The WAS7227Q has low bit-to-bit skew and high
channel-to-channel noise isolation, and is compatible
with various standards, such as high-speed USB 2.0
(480Mbps). Each switch is bi-directional and offers little
attenuation of the high-speed signals at the outputs. Its
bandwidth is quite marginal to pass high-speed USB
2.0 differential signals (480Mbps) with good signal
integrity.
The WAS7227Q is featured with special circuitry
on the D+/D-, which allows the device to withstand a
VBUS short to D+ or D- when the USB devices are
either powered off or on.
The SEL/OE pin has overvoltage protection that
allows voltages above VCC, up to 7.0V to be present
on the pin without damage or disruption of operation of
the part, regardless of the operating voltage. The
WAS7227Q is also featured with smart circuitry to
minimize VCC leakage current even when SEL/OE
control voltage is lower than VCC supply voltage. In
other word, there is no need of additional device to
shift SEL/OE level to be the same as that of VCC in
real application.
The WAS7227Q is available in QFN1418-10L
package. Standard products are Pb-Free and
halogen-Free.
