Description
The PI3USB2117 is a single differential channel USB 2.0 Switch.
Industry leading advantages include a propagation delay of less than
250ps, resulting from its low channel resistance and I/O capacitance.
The switch is bidirectional and offers little or no attenuation of the
high-speed signals at the outputs. It is designed for low bit-to-bit
skew, high channel-to-channel noise isolation and is compatible
with various standards, such as High Speed USB 2.0 (480 Mb/s).
In addition to isolating D+/D- pins from a USB connetor, Pericom's
PI3USB2117 solution provides Electrostatic Discharge (ESD)
protection, up to 12kV per the JESD22-A114D specifi cation.
PI3USB2117 also offers overvoltage protection, per the USB 2.0
specifi cation. With the chip powered on or off, all I/O pins can
withstand a direct short to the Vbus pin on the USB connector. In
order to enable the overvoltage protection feature, the user must
add a 100ohm resistor between the power rail and Vdd pin on the
chip, pin 9.
